A long weekend with nothing to do, and a 40% price drop on Surface Pro 128GB translated to one of these ending up in my hands a couple of days ago (along with the Type 2 Keyboard - which is perfectly okay to type on, tbh).
Some quick observations.
1. 1920x1080 display on a 10.1" screen is incredibly sharp.
2. Device is not the most ergonomically friendly out there; mostly due to the angle of the screen. I imagine Surface 2 Pro, with its two staged kickstand would fix that to a large extent.
3. Not sure of using this as a tablet device for typical "tablet" tasks and in all honesty, the pro might be a bit overpowered for that; though I can see a potential use when coupled with a USB 3.0 docking station.
This would make a perfect device that you convert into a full blown desktop by plugging in a single cable into the lone USB 3.0 port and have it running two displays, a full size keyboard and mouse (and the device itself does duty as a third screen on which sits your email/calendar/things you need but not need); and then, heading to a meeting or at the end of the work day, unplug that one cable, and its a easy enough device to carry without feeling like you are lugging a beast.
Plan to use it in various use-cases during the week before deciding if I stick through with this or put it on eBay. Getting this device the other day did prompt me to stick my MacBook Air on Craigslist and it sold within hours; recouping entirely the costs of this, so at least I'm not out of pocket on the frivolity of a second computer
