MacBook Pro 15" because our entire org runs on MacOS. It's fantastic since we have Linux/Unix infrastructure and also have iOS/Android apps to build. It's great for everything we do and they're super reliable.
Can't imagine working on anything else.
Some of my colleagues have an iMac + MacBook Pro setup. The iMac is at their desk and the MacBook Pro is for taking to meetings and working from home.
Xiaomi Mi Laptop
I switched from Macbook Pro 2013 to ~$1,000 Xiaomi Mi notebook pro (i7, 16GB, Dedicated GX card, better battery, HDMI port, 15inch, Mac like keyboard and touchpad, fingerprint reader). I run a right-swipe virtual machine and run chrome all day without issues. It's a good for 3 years machine. Screen is fullhd though.
None. Laptops offer terrible value for money for the sort of work I do. I have an MS Surface Pro for when I want to work on the move (which is surprisingly great for what it is and the keyboard is far more comfortable than it has any right to be), but not for day to day work.
I own a macbook air and a custom-built workstation running Debian. The workstation was built almost 7 years ago, remains my primary machine for work, and it continues to provide ample performance. On the other hand, the macbook Air cost as much as the workstation, I never enjoyed using Mac OS, and find myself longing to replace it with one I could run Debian on.
In hindsight, I shouldn't have bought the macbook. There seems to be a second market for used laptops, though, and so I may sell it.
Dell Precision M3520. Good keyboard, good size, good complement of ports (3x USB3.0, HDMI, Thunderbolt, NIC, even VGA), excellent performance (i7 + expandable RAM + Quadro graphics), nice 1920x1080 screen too. Leagues above our standard XPS 13s for usability, if much larger and heavier. I have it running Ubuntu 18.04.
System76 Bonobo. My day job involves cloud (k8s) GPU stuff and it's the only linux laptop I could find with two Nvidia GPUs. The trackpad sucks ass, the power connector is stupid. It's full of batteries that only provide an hour (max) of battery and it's only a laptop in the sense that it can (technically) fit on my lap.
A coworker recently got the single GPU Serval, and I could see using that daily. Ubuntu 18.04 is a great desktop OS. I have tentative plans to take apart my Bonobo, remove the batteries, put power supplies inside with a standard power plug out the back and cut out the trackpad and fit in an Apple trackpad.
LXD+QEMU makes it a pretty nice machine. I almost don't miss OSX and this [0] project has solved a lot of those issues.
8 years old HP Pavilion g6 with 1.9gHz dual core with 2.4gHz boost, overclocked to 3.0gHz. Upgraded to SSD, 8GB RAM and run Chrome off a Ram drive. Windows 10.
It just won't die. I tear it down once a year and clean it. I've started transitioning everything off of it to an Ubuntu VM on a home Proxmox server with a pass-through GPU, provisioned with 4-core 4gHz processing power.
I guess the keyboard on it is what I'm most comfortable with. It's gone through a couple batteries and power bricks, and I keep expecting it to not boot up one day.
If I had to get another laptop, I would probably not make much of the monitor, and plug in my HD TV like I have now. I would probably look for one comparable in size... For the keyboard. Laptops have wonky keyboards sometimes.
2018 15" MacBook Pro (i7 2.6GHz/16GB/1TB SSD/560X 4GB) because I prefer macOS for the majority of my work, despite being able to work on basically any machine. The touch pad is still amongst the best I have tried, it's fairly reliable compared to the Dell XPS 15 I used to use, great build quality, and it integrates nicely with my other Apple peripherals. Realistically, I could get work done on about any machine since most of my work involves SSH'ing into different hosts running different suites of software in order to build kernels, drivers, and other configurations of OSes that get put on target hardware.
For the last 5+ years I've been using ZenBook UX32LN - it's still the best machine I've bought (I've replaced my MacBook 2012 for it with no regrets).
I was working linux for these years on it, but switched recently to Windows 10 + Microsoft's linux subsystem thingie - it works pretty nice - once this machine will totally break I think I'll consider one of Surface Books since the OS is not a problem for me anymore.
Why I work on it? It's fast (SSD + i7 (even if it's an outdated model) + 12GB of RAM) makes it really reliable for fullstack development. Besides that, 13" Screen is enough for me, makes it pretty mobile machine.
15" MacbookPro because it just works, integrates perfectly with phone and watch, great support etc. And after 3 years I can still sell it for a good price.
I mostly work on a desktop, but when I travel, I love my T480. It's user upgradable so it'll last a while for me, and it has removable/replaceable batteries. On a full charge, it lasts like 30 hours when writing, programming, etc. Hardware support in Linux is great (with the exception of the fingerprint reader, which is in progress), and there's even an option for a pretty nice screen.
MBP for work like almost all tech companies provide nowadays; and for personal/hobby dev work a Lenovo Ideapad 720s, with Antergos Linux loaded on it (dual boot with Windows).
I have to say that installing Linux on that laptop was not the easiest, multiple challenges including wifi drivers and trackpad drivers issues. But once it's all fixed up, it works well. I chose it for a combination of low price and lightweight.
2017 MacBook Pro 15" (i7/16GB/1TB SSD) running Mojave.
Why? Because my top-end 2013 MBP 15" died and I couldn't find anything I liked better. But it was still plenty fast.
I want to flee macOS, as Apple doesn't truly care about it anymore, but I can't tolerate anything else. I want to tolerate Windows 10 as a main OS but I can't get myself there, yet.
Mid-2012 13" MacBook Pro. Because I can (and have) easily take it apart to add SD storage and replace its previous hard drive, or battery, or etc. It pairs perfectly with my other devices. It can handle most post-production software I throw at it.
It's also a tank, built in the era before Apple got the idea that they can make their machines more flimsy and make more money.
A Lenovo T470s. Works with linux out of the box. Able to take anything I through at it. A screen resolution that does not hurt my eyes.
Dell xps-15 running Windows. I chose it to replace my MacBook pro because it had an Nvidia GPU, a good selection of ports and a great screen. I also use a Lenovo X1 carbon for the small amount of Linux work I do because it works well with Linux without any fuss.
If I was buying a new laptop, I’d look hard at the Lenovo Thinkpad X1 Extreme.
I use a laptop at the desk, with a monitor and proper keyboard / mouse and task chair. I use MacBooks mostly because of OS X and the need to interface with Linux and Unix infrastructure. I don't need horsepower on my workstation, because all the CPU or disk IO I need is in the data center.
Lenovo X1, because it's tiny, dependable, powerful enough and not a mac. Mine runs ArchLinux.
Chromebook because it runs all day on a charge and I ssh into the many servers at cloud providers to perform the grunt work. Apps on Chrome are sufficient to whip up documents, etc if and when required. I use a desktop for editing images and running tests.
Now: X1 Carbon 1st gen. its tough as old boots and light as a feather. sadly its also pretty old now
Soon: Undecided, was going to be an x1 extreme until they put the price up by £500 for no reason so itll likely be an xps15 or a 13-14" laptop and an eGPU next
Macbook; It's just more supported for a lot of software which made me make the switch.
Thinkpad w520 because I replaced the cd drive with a second hdd and the original drive with an ssd. It still works like a champ. (i7 2760qm,quadro 1000m,12gb ram). It set up exactly how I like and it's predictable even in failure.
macbook air 13" it's all the power I need for web development (Rails/Laravel) and I can buy two for the price of a pro. Once the keyboard issue is resolved and the esc key is back I might go for a pro next time.
dell latitude
i5 7th gen 2.5Ghz, 8Gb RAM, HDD 500Gb, 1366x768 HD display
second monitor Dell 1280x1024
Windows 10 enterprise 64bits
desktop, because it's fast and ergonomic
2015 15" macbook pro. It has sufficient computing power for software development and linux server management. I've been a mac/linux user for all my adult life. Simply put, I enjoy the hardware.
HP Omen 17" i7 8th generation Windows 10 Home because it was the most power for the least money and has a reasonable screen size. Windows because I need to able to run Visual Studio and MS Office
I use a ThinkPad T470s for my work, with Windows 10 Pro. Used to have a MacBook Pro 2015 but didn't like the design of the 2016+ models. I wouldn't turn back.
2017 MacBook Pro, TouchBar
I like it! It does the job. I don't mind the keyboard either, but day-to-day I either use a Filco Majestouch 2 keyboard or an Apple Wireless keyboard.
I don't use a laptop for my actual day job, for all hobby coding is done on a 2016 X1 Carbon. It is durable, light, and was relatively easy to install Linux on.
System76 Gazelle because "it just works". Flawless sleeping, good battery life, easily upgradable, but a trackpad that leaves you wanting more.
Desktop workstation for most of day work Laptop(Dell M5510) only for meetings, I prefer a 12 inch, slim laptop, but my company only provide 1 option....
MacBook Pro 2015. Because work gave it to me.
All my desktops are Win10.
2015 MacBook Pro because of a UNIX-based operating system with a decent UI and well-designed hardware that works reliably with said OS.
Dell XPS 15. Now 2 generations old but it's still faster than me. Be nice to have more than 16gb RAM but hey-ho.
MacBook Pro (Retina, 15-inch, Mid 2015), because its the one my company gave me.
For the 3D content creation and animation that I do, I cannot afford a laptop that can handle such work. So I use a desktop only.
dell latitiude 5491, its a 14" beast running the awesome 8850H processor and it has dramatically improved my productivity, very solid built as any other latitude
Dell XPS 13 (9360) with Debian Sid, works flawlessly. Though some initial setup is required: turning off DBC (.exe available at Dell's support site) and using latest ath10k firmware from github. After that it's a laptop of my dreams ) Light, small, 13" screen in a typical 11" laptop chasis. The only drawback is soldered RAM, I have a 8GB version and Angular's reloader leaked memory, so I had to restart it every few hours.
Other than that, I've dropped it from my height on a tiled floor by accident, it landed on a corner. I've unbent screen part with pliers, and fixed cracked hinge with superglue, soda and steel wires, and that was it. Alternative would be to order a part of the chasis, but it would take too long. During the repair I've also weakened hinge resistance a bit, it was too strong for non-touchscreen version; should have done it from the start I guess.
