Over at All Things D, Walt Mossberg has reviewed Asus’s Transformer Prime, an Android Honeycomb tablet that has an optional, attachable keyboard. He likes it, sort of–although he likes the iPad better, and has multiple reservations.As someone who likes to use an iPad as a PC, I’m intrigued by Asus’s convertible design. It’s designed for folks like me who like tablets but also like clicky QWERTY keyboards. But I’m also worried about Walt’s battery tests, which showed the Prime running for a little under seven hours on a charge, vs. a little over ten hours for the iPad. My single favorite thing about the iPad isn’t the size or the weight or the apps–it’s that Apple claims ten hours of battery life, and–in my experience–delivers it.
Asus, on the other hand, says that the Prime will run for eighteen hours on a charge, a figure which might have me whipping out my credit card even now if I thought it reflected what I’d get in the real world. As Walt explains in his story, the fact that he got under seven hours requires some explanation: He tested using a setting called Normal, which Asus now says really emphasizes high performance. If you were trying to eke as much life as possible out of the tablet, you might be able to get more.
But what do you think the chances are that you’d really get eighteen hours?
