Jaffer Hasnain writes about the Core Duo Gateway Tablet PC. PCMark05, Super Pi, 3DMark05, and HDTune benchmarks are included in the review. The section which caught my attention the most was the writing about the battery life.

I chose to upgrade the battery to the optional 12-Cell, which would provide more battery life at the cost of more space taken up, however I did not mind this minor sacrifice because I did not want to end up without a laptop because of a battery that could not stay away from a desk for less than a few hours. This 12 cell lasts almost 5 hours under normal usage w/ wireless on, and internet browsing, with 40% tablet usage. When being miserly, and low brightness and no wireless, the laptop can almost hit 8 and a half hours.

I agree with Jaffer. This is amazing.
