I've had the original Pro since initial release and it has been a reliable everyday and travel workhorse. I use it mostly in tablet mode and with some difficulty (and the pen) use PS3, Canon's RAW converter, MS Word, MS Excel, etc. but it's really best when using the metro apps which are touch-screen enabled. It will become unstable and need a re-boot if I have lots of apps open and lots of tabs in metro IE. Upgrading to the same spec Pro 3, what will I notice most? Obviously, I'll have more screen real estate. Does this help functionality much? I run out of room when using the on-screen keyboard on the Pro 1. Will the Pro 3 be more stable? Quicker? Any other differences worth mentioning?
