Happy customer.
I own a surface pro 2 256gb model. I quite frankly couldn't be happier with the device.
I'm a photographer and it can be stashed in with my equipment wherever I go without a moments thought, and is more than capable of editing and managing a heavy work load on the go, (the battery does brilliantly).
Its a brilliant way to show clients images, its also great for tethering, and editing with a pen ads a dimension to the experience I rather enjoy.
Granted this isn't everyone's use case but its certainly a lot better than people give it credit for.
In regards to the RT model it certainly doesn't have the app selection and is far from perfect but there's some great multi tasking features that neither iOS or android have that are incredibly useful. Aswell as a rather refreshing change from a standard icon based ui. Personally if I was in that market I would look at something with an atom chip in it however.
These products get better and offer features (in hardware and software) that the competition doesn't, which only serves to bring choice to the consumer... not a bad thing.
