Hi, I'm giving a lot of thought on buying the aspire one with 11.6", the one with the Z520 Atom processor and 1gb ram... specially because I don't like small keyboards and I love the big resolution it has, but I'm a little concerned about the CPU and the RAM memory... is it enough? I don't want to do anything special, but would I be able to do all those at the same time: listen to music, have some PDFs open, browse on the web and IM people? This would be on Ubuntu, would it get too slow doing all that stuff? By the way, can I really see 720p videos on it? Thanks a lot in advance guys!
