Though not quite as cheap as the Asus Eee PC from a couple weeks ago, the Acer Aspire One is one of the top-rated Netbooks (there's a contradiction in terms), and you can get it for just $309 shipped--no rebates required. Hey, they gotta do something to unload these lemons, right?
I kid, I kid. While I still don't see the appeal of a PC with a tiny screen, tiny keyboard, tiny amount of storage, mediocre battery life, and limited video-playback capabilities, at least the prices are starting to get more attractive.
This particular model comes with an Intel Atom processor, 8.9-inch screen, 8GB solid-state drive, built-in Webcam, 5-in-1 media reader, and 512MB of RAM. It runs on the Linpus Linux Lite OS and includes a three-cell battery, which Acer says is good for up to three hours. CNET got 2 hours and 14 minutes in its battery-drain test and awarded the Acer three stars out of five in its review (which called it "the best all-around Netbook we've seen for less than $400").
Obviously the appeal here (and with any netbook) lies in the lightweight design (the Acer weighs all of two pounds) and low price. If you need a secondary PC for around the house or short trips or whatever, here's your chance to score One for $70 less than usual.
