Under different circumstances, I might consider a netbook strictly for casual "away" use, but this is going to have to serve as my primary computer at times, and the tiny screens aren't compatible with my not-so-great vision. As a matter of fact, I was considering a netbook a while back for just that purpose, but things have changed.
At any rate, what I have now -- laptop has just a 1GHz cpu, and my current desktop (until I get around to tinkering with some others I've been working on) is only a 1.25 GHz Athlon -- will probably be outperformed by almost anything recent!
