Long time SP1 owner now making the jump up to the SP3. I have used the SP1 as my primary work device now for about a year. Using it in conjunction with a Lenovo USB 3.0 Dock at work and home powering multiple monitors, Ethernet, etc. Spent the day getting it setup at work and now finally getting a chance to play around with it at home. First impressions. Fantastic Build! Thin! Size is a dream! Love the Stylus (N-trig, go figure) Loving the size of the keyboard and touchpad. Kickstand! Yeah, that is what I am talking about. Not one gripe at the moment! I was very hesitant to move to a N-trig device. I still have a real bad taste in my mouth from the HP Slate 500 fiasco. I told myself not ever again, I think I even blogged that. Ooops. Don't tell anyone, but I might be converted. Anyway, I am very impressed! Still playing around with the hand writing, but over all very impressed. Glad to be part of the club. Now I need to get caught up on the SP3 threads.
