Perhaps consider an acer timeline?...DON'T buy a netbook because it's trendy.
Great wording. These things have
became pretty trendy just to have...like an iPhone.
I think it's important to note that these things are comparable to 1,000Mhz Pentium4's (maybe P3's), have very low 3D graphical abilities (2D has it's limits too), and were released with Linux based OS's solely on these small limitations. Now that they're being sold with WinXP, that doesn't really improve their performance, but rather not force a user to retrain themselves into yet another OS.
But they're very low dollar up front. If you know what they're good for and can use it in that confinement, they're very desirable and priced right. But to have the name "netbook" makes one simply think they're smaller "Notebooks", which they are far from.
An Acer Aspire AS5735-6694
(deactivated) is still under $600 and may still be able to be picked up at a local BestBuy...on sale for clearance. It's an actual laptop, doesn't break the bank, and I've gotten 4 hours out of one charge as delivered with the 6-cell (just watching movies on a plane and web-browsing on the ground. Maybe 2-1/2 if I game).
