I'm looking to buy a used laptop on eBay sometime in the next few weeks, but I don't even know where to begin when looking at specs. It needs to be very inexpensive, $50-75 max. I'm comfortable with Windows as long as it's not Vista, but I'd consider Apple products too (as long as there's not too much of a learning curve for someone with zero experience with them). This will be a workhorse laptop, so looks and fancy features aren't important at all. I do need it to have a fairly recent operating system and the ability to connect to the internet (wifi preferred, but I could use a cable if necessary). Battery life doesn't matter as long as I can keep it running plugged in. The most important thing for the work I want to be able to use it for is that it be able to run a LOT of tabs streaming all at once, without locking up or crashing. A large screen size would be nice, but not essential. I know there's no way of knowing what will be listed until it shows up. I'm looking for help with general specs in terms of what is most important to having a computer that can do this. RAM? Memory? How much will it take? I really don't know what gives a computer the ability to multitask and stream under heavy use. I also would love it if anyone could suggest Make/Models to give me a starting point on what are known to be good laptops even though they're old - and the opposite, lemons to avoid! Thanks!
