It's a nice reader, but there's nothing on the iPad I look at and say, 'Oh, I wish Microsoft had done it.'

Microsoft Research has a thing called the Sense Cam that, as you walk around, it's taking photos all the time. And the software will filter and find the ones that are interesting without having to think, 'Let's get out the camera and get that shot.'
