I just bought DS a netbook for high school graduation, so I did a lot of research on them. He'll be using it for college classes.
We ended up buying a Asus 1000HE from ZipZoomFly.com (
Amazon has a good price on it too). Be careful that you look at the HE model, not the HA model. There's a small difference in price, but the HE model is much better.
There are several reasons we chose this particular one:
*9.5 hour battery life (some netbooks only get 3 or 4 hours)
*Intel Atom N280 processor (currently the fastest one)
*1 GB RAM, and VERY easy to upgrade to 2GB. This makes it run faster than other netbooks. Costs about $25, and time involved about 5 minutes. There are plenty of videos on YouTube that show you how to do it, if you don't know how. Some of the netbooks are very hard to upgrade the RAM on. For example, on the Dell Mini, you have to remove the entire keyboard to do it (which also voids the warranty).
*Wireless N, as opposed to the older wireless standards.
*Chiclet style keyboard
*10 inch LED-backlit display. We looked at the 8 and 9 inch ones, and they were just way too small for comfortable use.
*92% size keyboard...some of the netbooks have very tiny keyboards, which are hard to type on.
*Bluetooth compatible.
There are probably a few other reasons I chose it, but those are the ones that come to mind. I suggest going to BestBuy and trying out a few, so you can see what size of display you're comfortable with. However, you're going to get the best price by buying online. BestBuy doesn't even carry the model I bought, since it's newer to the market.
