Ha, well no less than 3 weeks after I bought my Surface Pro I sold it! Instead I bought the Ipad Air i originally intended to buy, stupid or what!
Reasons for selling? Too heavy, too hot, rubbish battery life (struggled to get 3 hrs), and desktop mode just too small on a 10 inch screen.
Trying to use Photoshop even with the amazing artdock was a frustrating experience. If you wanted to draw on your lap ideally you needed 3 arms: one to hold it, one to manage the artdock and the other to hold the pen. And of course the Photoshop interface is tiiiny on that screen. Eye strain? Yes indeed.
I now use Procreate on the Ipad which of course is made for touch. With the wacom creative stylus it feels just as good as the wacom tech for the surface pro and there are none of the compromises I had to put up with on that device.
I do miss having it, all that said. It was amazing having all the power in a device that small and portable.
Maybe next year when they release the Surface 3, when it should be lighter with better battery, then i'll reconsider.
