You will not miss the RT at all. The Pro wakes from sleep very nicely. It boots in 15 seconds or less. Its a little heavier but worth every ounce. Its an ULTRA Ultra-book. Go for it - you will love it. I have not used the pen except briefly. It seemed ok, its just not part of my daily tasks and not something I love. The Thinkpad Tablet2 has a mini version of the Wacom pen and it fits inside the device. Its a clover-trail 32 bit pro device. But its like $649 vs 899.....I think I am going to get a Pro to replace my RT... 80% because I want the active digitizer screen and 20% because I want to run legacy apps. I suspect I'm going to miss the smaller size of the RT, the fanless/cool operation, and the Instant wake from sleep. We'll see... maybe TODAY.
