I have to say, after my laptop broke down, I've been left with my Aspire one netbook which has a C-50 processor, and I am not happy with it at all.
Maybe it's because I've gotten used to using my laptop, which, although was only Dual Core 2.40 ghz, allowed be to browse through many things while watching an occasional video. My netbook however, cannot maintain browsing from 4-5 tabs without constant lag, which makes reading news articles or looking through forums quite uncomfortable. Gaming, obviously, is also impossible. Although a netbook IS smaller and easier to carry around, unless it is just for office work, i would recommend paying the extra $100-$200 to get an ok laptop.
