The thing you need to consider when you're thinking of tablets is apps.
There are currently thousands of App Store apps optimized for the iPad, but just under 200 Android apps optimized for tablets.
Another thing is, not all apps on the Android market will work with your device. On the App Store, virtually every app (iPhone/iPod Touch and iPad) will work on the iPad.
The makers of the Android (and other OS tablets, but you want to get android if you don't get an iPad) boast of better graphics and processing power, but what will all that power be used for if there's only 200 apps currently out for the Android tablets?
