Linux, The Perfect Gift, on Sale Now at Amazon.com

Amazon has three Linux-based netbooks on sale for the holidays, at up to 24% off.

ASUS Eee PC 900 8.9-Inch Netbook -- $417

This one is the one I'd get if I were in the U.S. At 24% off retail, it's a steal.
It comes with:

• 1 GB RAM, 
• 20 GB Solid State Drive, 
• Xandros Linux, 
• and a 4 Cell Battery

ASUS Eee PC 1000 10-Inch Netbook -- $481

It's only 3% off, but has a larger drive and better battery:

• 1.6 GHz Intel Atom N270 Processor, 
• 1 GB RAM, 40 GB Solid State Drive, 
• Xandros Linux, 
• 6 Cell Battery

HP 2133-KX869AT 8.9-inch Mini-Note PC -- $533

This one is more expensive, an older base model (with Via chip), and only 8% off, but it has had wonderful reviews, especially for the keyboard. I wouldn't want the hard disk, though.

• 1 GB RAM, 
• 120 GB Hard Drive, 
• Suse Linux
