[Updated: After using this for a couple of weeks, I'm still happy. But, the modest lagginess is a bit more noticeable. If you're one of those people whose blood pressure rises when the driver in front of you is doing 55mph and you want to do 57, you probably should buy a beefier box.You can reduce this effect by using a browser that lets you disable JavaScript on various sites. A lot of this is crap that slows down your machine but produces no value (for you).]My version has Ubuntu (Linux), 16GB RAM and 512GB storage. There are other sizes, and I think you can get it with MS Windows for about $30 extra. I think I paid about $170.The storage is NVMe and quite fast. I haven't benchmarked it, but the RAM seems fast as well. Probably the Celeron CPU is the choke point--four cores and not too fast. It's fine for run of the mill web browsing, and things like videos seem to work without stutter. If you're running a fat web app with lots of JavaScript, it might seem noticeably slow. Probably wouldn't be good for intensive gaming or image/video processing work.The form factor is very nice. There's a fan on the bottom, and it does make an audible sound in a quiet room. Probably similar to some laptops you've used. If there was other background noise, I'm not sure you'd hear it at all. (If you have noise-cancelling headphones, they kill the fan sound entirely.) The fan doesn't seem to be software-controllable.It's delivered with a recent LTS Ubuntu install, ready to set up. If you're paranoid, or just want the latest non-LTS version, it's an easy install from a flash drive. I haven't noticed any odd drivers being needed or anything like that. It's all Intel, aside from the ethernet chip, which is Realtek.Overall, I love it. If you're going to be disappointed by a lack of "snap" under heavier workloads, you might want to be with a more expensive CPU. (Generally, using MS Windows would require more CPU, versus Linux, so take that into account.)
