We purchased one Rt and one Samsung ativ 500. Love the form factor and build quality of the RT, not so much for the Samsung. Samsung's screen is nice and the digitizer has been key to our use case but the keyboard dock not working consistently is the big killer. I like the larger screen of the Samsung but overall for day to day use it's a bit large when using in tablet mode. I'm now planning to return both and get two Pro's when they are released. I'm fairly confident the PRO will be it, with increased resolution, digitizer and i5, but battery life will a deciding factor. I'm hopeful I will get 5 + hours with my use case.'''' I fly coast to coast monthly and like the battery life of tablets, but would take 5 hours of productivity over 9 hours of Angry Birds. I usually use my MB until the battery dies... 3 hours... then switch to a tablet.
