I'm in the market for a Linux friendly ultralight laptop to check web apps and run terminal, nothing fancier then that. Do any cheap systems exits these days? I was looking at a chrome book but apparently the mediatek chip doesn't play nicely with FOSS.
Can confirm, I use an old HP elitebook from work. Battery life is great, beats my wives new lenovo. More than powerful enough to browse the web and play in the terminal. Also only gets hot if I run a game on it; I wouldnt advise that though.
I have a second-hand Thinkpad T480s that I love, I bought it for 250$ on ebay and replaced its battery because it was fried (+40$). I use it for school and it works flawlessly, around 8h of battery life in a well-configured OpenSUSE Tumbleweed. According to the specs sheet it shouldn't be, but for some reason it is noticeably lighter than a friend of mine's MacBook Air 2021.
What I really love about it is the ThinkDock Ultra (iirc 30$ on ebay), which lets me place the laptop on my table, and by just sliding a piece of plastic, it connects all of my peripherals in a second. I love this laptop so much that I'll use it until it dies so hard that it can't be fixed at all.
When you say "couch" my first thought is a recent-ish Celeron or Pentium Silver fanless laptop. Performance akin to a Core 2 Duo but no fan to get blocked sitting on the couch. Like the Latitude 3210(?)
Laptops that appeal to me are often bottom breathers so it's one thing I miss from my old MB Air.
I bought a used Lenovo ThinkPad X240 Laptop i5 | 8GB RAM | 500GB HDD | for 50$ as a couch laptop to run Linux / Python code. I can browse the internet and it’s light.
I bought a refurbished dall latitude 7490 for like 270$. For the price it's a powerful machine, 16gb ram and i7 processor. Installed fedora on it and I'm in love with it. For the price it puts out the power I need for software development.
What price bracket are you looking at? The two laptops that I normally use in that situation is a used Thinkpad X1 Carbon I got on eBay, and a HP Dev One that works pretty well for that.
The Thinkpad link that was shared below looks pretty nice, they tend to be fairly cheap and easy to get replacement batteries and parts. There's a lot available in that $150 to $200 bracket on eBay.
Edit: I just saw it's 14", so a bit bigger than what you wanted. You can filter by screen size and price on eBay to give you an idea of what you can get. You may need a new battery depending on the age, so keep that in mind.
What about something like the Thinkpad X201? It's not ultralight but it is quite small.
Other than that I'd probably say a Chromebook with a Linux install. Second hand they are quite cheap and can likely do what you are after. A lot of them have passive cooling which is nice for a couch device. I was able to install libreboot on my C201P quite easily and now it just runs a traditional Linux install
I prefer the T480 series (imo Thinkpad went downhill from there onwards). The non-s is a great off-road laptop, but for what OP is asking, the T480s seems like a more sensible choice.
As others have mentioned, secondhand laptops and surplus business laptops are very affordable and probably better value for the money than a chromebook. My understanding is that drivers for things like fingerprint sensors, SD card readers, or oddball Wi-Fi chipsets can be issues to watch out for. But personally I don't care about the fingerprint sensor and only the Wi-Fi would be a major issue to me.
A couple years ago now I picked up a used Acer Swift with 8th gen intel and a dent in the back lid for something like $200 to use as my "throw in a backpack for travel" laptop, and it has been working great. In retrospect, I would have looked for something with 16GB of RAM or upgradeable RAM (8GB soldered to the motherboard, ugh), but aside from that minor gripe it has been a good experience.
I use Brave pretty much just for that purpose, while I use Firefox to browse everything else.
There isFirefox PWA, but it feels like such a shitty hack (don't get me wrong, it's not badly made, but they're forced by the circumstances to make a setup process that is one big headache) that I'd rather have a browser that has official and solid support and it also doubles as my browser to test web content on Blink, so it's a win-win for me
I picked up a Black Friday Lenovo ChromeBook (Flex 3) for US $160 and use it essentially the same way you describe. You can load up a Debian-based Linux environment within ChromeOS. It's basically my web-capable thin client.
I have a framework and love it but it's probably not the best option for this. It's kinda overkill and they can get a bit hot and loud. More of a desk laptop than a lap laptop IMHO. Also depends on how long you need the battery to last but this is reportedly better in the newer models.
I bought a used HP Elitebook on eBay for a similar purpose. I can browse and do video calls on a bigger screen when the fancy strikes. Pretty much any used business laptop should work. I think I paid about $300 for mine and I paid extra for particular hardware I thought was neat but you don't have to. Only thing to keep in mind is the battery will likely be pretty worn.
Personally, I'm waiting to see how support for the M1 Macbook Air and Thinkpad X13s develop. I have a MBA already, so I'll probably throw Asahi on it eventually, and then wait for the ARM wars of 2025.
I'm not at all a fan of the keyboard on the MBA, but being passive and 13" is perfect for the couch.
The ultimate couch laptop will be an M1 MacBook Air as it has no fans and a suped up phone chip so it doesn't heat. It also has amazing battery life... But it's still pretty expensive and it cannot be repaired. Otherwise old MacBooks should be pretty good because most of the Intel models used relatively low end chips because their thermal design was so limited
I went with a used ThinkPad yoga 370. It still only has a dual core while the following Gen has 4 cores, so it seemed there was a price gap. It has thunderbolt 3 for when I want to switch to a bigger screen (with a cheap USB c dock) and USB c charging. Also I wanted to try a touchscreen on a laptop. I should be able to upgrade the single ram stick in it at some point. Running arch with sway without problems.
Edit: I had a x240 for years before. It was fine but I appreciate the higher resolution of the 370, even if I ended up using fractional scaling as it was just a bit too small.
