It's a bit more expensive than the Lenovo but you get a slightly faster CPU and a 8700mAH battery. Plus you also get 802.11n and Bluetooth connectivity. Right now it's going to replace the old Compaq notebook connected to my LCD TV. My only concern is how fast the computer will be with the Intel Atom N280. From Passmark, here are some CPU benchmarks:
Core2 Duo T8100 @2.1GHz (Sony Vaio CR420E) = 1,269
Core2 Duo T7200 @2.0GHz (Dell Latitude D820) = 1,058
Core2 Duo T5600 @1.83GHz (Dell Inspiron E1705) = 1,019
Core Duo T2300 @1.66GHz (Mac mini) = 803
Atom N280 @1.66GHz (Asus Eee 1000HE) = 316
Pentium III-M @1.133GHz (Compaq Presario 1722) = 185
Pentium III @533MHz (generic desktop) = ??
486SX @25MHz (Gateway Colorbook) = ?
The old Compaq notebook is pretty slow but it only had 512MB of RAM and probably a slow 20GB HDD. Hopefully with 2GB and a 5400rpm HDD, the netbook will be 2x faster. The T8100 in my Sony is pretty fast but some 3D games run sluggishly on it; probably it's due to the crappy built-in Intel graphics adapter.
From Intel's website, the T8100 also uses 35W whereas the N270 only uses 2.5W. That's why I'm only getting <2 hours of life from my Sony with a 5600mAH battery.
