I picked up a base model this morning at Best Buy - literally the only store in all of Upstate NY that had inventory (this includes Canada, and 120 miles east). I had to go to the MS store for the keyboard/pen, but this device is fantastic from a build/quality/battery life / performance standpoint. I can't wait to walk into meetings without asking WiFi passwords or credentials going forward with LTE setup.
Anyone considering, if you understand limitations of WOA, you'll be very happy with the device. I had a NovaGo when it came out and returned it, unstable and awful performance all around. I'm blown away by the progress in such a short period. Not only that but the quality of this device is amazing. I love the MS Whiteboarding app, I'll get some use out of this going forward for sure.
