I went round to Currys today & checked out the Android tablets on display. I must say, Asus has a big winner in the form of Transformer Prime. It's lighter & slimmer than the iPad and has gorgeous premium looks with an equally gorgeous keyboard. The screen is super slick, at least as good as the iPad's (if not better) & far better than the Sony, Samsung & Motorola offerings on display.
Android now has a decent collection of apps, although not as extensive as iOS.
If Asus is able to make enough tablets to keep up with demand, I can see a serious dent in iPad's market share this year.
