I have an XO laptop as part of the OLPC (One Laptop Per Child) Give-1-Get-1 program.
The following image compares the XO to a Zune 30.

Here's the XO compared to an IBM Thinkpad T42 (15" display)

Here's what ZuneScene looks like using the Opera web browser. This picture (taken with my cellphone's camera) doesn't do justice to the absolutely crisp screen.

A shot of the XO's "Sugar UI" desktop and partially twisted.

Here's the XO in "ebook mode". The screen can be oriented for both lefthanded and right handed users.

I'll even throw in a 2GB SD card preloaded with Ubuntu Linux, Open Office, Firefox, and a few more goodies.
I'm looking to trade it for an EeePC, or any other reasonable offer.
