This is exactly why you see so many netbooks for sale on craigslist. People bought them due to the hype and the price, then realized they are too slow to do a lot of things, and everyone started selling them.
They are great as long as you understand the limitations, say for a student wanting to take notes, type our reports, watch a non-HD video and use Skype for chatting while having a small cheap system. Anything over those basic uses, you are better off with a regular laptop configuration.
