obviously price doesn't directly equate to performance. Yeah when I said laptop I misworded that, I meant Windows OS machines. However when people are looking for a laptop, from experience I've found they are usually looking for something more versatile than a Chromebook. Even people who are shopping for their kids for school. Also, the Chromebook models I've seen have all had 2gb of RAM, for the price range I mentioned.. just to clarify.
While I agree with what you're saying in regard to operating system background tasks, and if I wanted something to serve a specific purpose I may consider a Chromebook, consumers generally seem to agree with me on this, as Chromebooks don't sell particularly well. This may be because of convention as well.. as Windows and Apple dominate the market and people don't really like too much change in regards to their systems. But I think another main reason is that people look to buy a machine that will be a multi-solution for them (or their kids). When you can get a Windows laptop that is that extra bit more versatile for roughly the same price, they've already made their mind up.
