$200 sounds pretty optimistic for a decent computer. I don’t know if you’ll be able to find anything that cheap. And even if you did, the specs probably won’t be that high so shelf life might not be that great. It’d be outdated almost as soon as you got it. Granted, you don’t need the most amazing computer in the world to run MS, so your best bet is probably to shop around and find the cheapest deal you can get. But if you want something that’ll last a few years, I would definitely recommend thinking about investing a little bit more to get a better laptop.
