But it's a sweet system. The 1000H version comes with a 10" screen, 1GB of RAM, 80GB SATA hard drive, a 1.6GHz Atom processor and weighs just over 3 lbs.
It comes with XP Home pre-loaded. I'd never used XP Home before but it does everything I need so far. It's pretty clean of bloatware. What extra software that is loaded is pretty much just the utilities to support the Asus.
The screen is only 1024x600 but is crystal clear. With a hardware button, you can change the resolution to 800x600, 1024x768 (compressed into 1024x600) and finally 1024x768 that scrolls.
The Atom has been pretty zippy. The latest BIOS (which came already loaded) even enables hyperthreading.
Unfortunately it doesn't have my beloved TrackPoint but it has a multi-touch touchpad similar to the iPhone. It shipped without the latest drivers but I downloaded them from ElanTech and they're wonderful. There's a clip on youtube.com demonstrating it. You'll also notice that they have Vista running on the 1000H!
I upgraded the memory to 2GB for $12.99. I'm not sure that it made much difference but for the price ...
Asus suggests the battery life is up to 7 hours. I can't vouch for that yet but it has run for hours even with the WiFi running. Speaking of WiFi, it supports B, G, and draft-N. Oh, and Bluetooth. And has an SDHC slot. And 3 USB 2.0 ports. And a VGA port.
There's a very active and supportive community around the 1000H here.
Here're some comparison photos of the 1000H, my beloved ThinkPad X20, and my work Dell D410.
