He also said it's as good as the iPad (2, I presume):

So far in my testing, battery life seems outstanding on the TouchPad. While I haven’t yet had a chance to run our full suite of battery tests on the tablet, I can tell you that in day-to-day, very heavy use, it performed excellently. On a typical day of rigorous testing (app downloads, 3D gaming, Skype calls, lots of web browsing, constant email work, Twitter, messaging, and more), the TouchPad went from 9AM in the morning to 12AM that night and still had 20 percent of its battery life. In lighter use, I left the device off the charger for 3 days straight and still had plenty of juice. HP says that the tablet is capable of 8 hours of web browsing, 9 hours of video playback, and 3.4 days of audio playback, and those estimations seem right on to me. As with the iPad and some of the Honeycomb devices, you won’t be reaching for the dock constantly.
If we're just going to compare mAh numbers and ignore user experience, than by all means, spec away.
