I bought a Toshiba NB205-N310/BN-G:
Toshiba mini notebook NB205-N310BN-G Laptops
I absolutely love my netbook because it gives me everything that I wanted in a netbook: 3G, 802.11 B/G Wi-Fi, Bluetooth 2.1 + EDR, 160GB HDD, Intel Atom 1.66GHz CPU, Windows XP Home Edition, 1 GB DDR2 533MHz SDRAM [upgradeable to 2GB] with a 5800mAh / 6 cell battery that lasts about 9 hours.
I upgraded mine to 2GB of DDR2 SDRAM and installed Ubuntu 9.10 Karmic Koala Desktop Edition. Running Ubuntu on the Toshiba NB205-N310/BN-G requires some major command line tweaking to get everything to work properly, but there are guides on the Ubuntu discussion forums to resolve technical issues. Karmic Koala is a polished Linux distribution for this netbook so the work to get this netbook's features up and running are fairly easy to implement. I prefer using Ubuntu GNU / Linux over Microsoft Windows.
The only downside is that it is expensive at $499.99 USD for a netbook. Otherwise, it is fantastic.
