Well, I'm enjoying it, but my expectations were quite low. Read the reviews and look at the videos closely--that will help.
For me it works reasonably well, though the interface is a bit quirky, and occasionally having only one hard button (instead of four) is an inconvenience. Though it's not heavy, I can't really hold it comfortably with one hand, which was a bit of a surprise. Having used this seven-inch device, I can't really imagine wanting to deal with anything larger. If anything, I'd be tempted to go with *smaller* devices in the future. (In some ways, my (work) Blackberry is easier to use, as it can be used one-handed.)
