Not sure. Don't know much about windows tablets. I like my wife's Android tablet.. If you don't jailbreak Apple devices they have a lot of restrictions, but they have less quirks.
I'm pretty sure they all have their own advantages, but I'd be happy to have any one of them. I'm certainly not going to complain about what's being given away for free.
The poll doesn't specify 'tablet', but rather 'device'. For those of us that have yet to join the 'smart phone' generation, would that be an option in the drawing? (Service plan obviously not included)
