iPad can do slightly more. But with WiFi on, I only make about 7 to 8 hours. That's totally fine, compared to my (now mainly replaced) UMPC Samsung Q1.
But it's still way less than I can do with PocketBook 360, Sony 505 or any other of my favorites.

But it's the WiFi that's doing that. Turn it off, and the battery life goes up dramatically. Using the iPad purely as a reader, and turning off WiFi and 3G, I get 20h+ battery life. With WiFi and 3G on, but infrequently used, it's perhaps 10-12h.
