Yeah I like it a lot. But that's mainly because i can do sketching, artwork, use C2, test the mobile games directly in preview, all on one device, without having to sit at a desk. I sit at a desk 8 hours per day at work, so it's nice to work on the sofa when I get back home :p
Personally ,,, and I love my surface pro for all the reasons tunepunk says..... the stylus is totally awesome for drawing and taking notes..... and I love that the device is really powerfull but.....;.
....it can be a pain using touch, and especially stylus, with C2 on the surface pro. there are loads of little quirks that make it tiresome after a while.. for me anyway. Also with regards to C3, chrome is not playing well with touch on windows / desktop, on surface devices anyway.
however I do do exactly as you saying and set up the surface pro at my local quiet cafe while my kids are at gymnastics on Saturday mornings, but I do this with Bluetooth keyboard and mouse so you could just as well use a laptop of some kind anyway,
what I am really thinking is that...
C3 is starting to look very usable and robust on android chrome right now....
.. and unless you are specifically looking for real stylus support then....
(assuming web gl compatibility and performance) any half decent, large android tablet with C3 , or one of the transforming chromebooks, might be the best solution going forward
(unless google fix touch on desktop/windows chrome which they dont seem to be in any rush to do)
