Last month I decided to purchase the Surface Pro - I've been a Mac user since I was 18 (now 26) so of course I was very unsure about switching!
Here it is straight out the box...
And a short clip of it in use...
The main reason for buying it I think, was the digitised pen; the fact that I can draw directly on it and it's not just a graphics tablet & monitor in one - its a whole PC. I can do everything on it.
As an artist, I love being able just to sketch, or do more serious digital art, and also do what I do most often : photo editing. The responsiveness and technique is better than my Wacom Intuos which I used with my MacBook Pro.
If Apple made a similar product then of course I'd jump on it, but it doesn't look like they're going to produce anything like this.
So for now I'm very happy with my purchase!
