FYI: This comes with the Touch keyboard, which doesn’t have moving keys. The Type Cover is the keyboard that has actual keys. A Type Cover from a later Surface Pro (3, 4) will work, but these keyboards are slightly larger than the Surface Pro 2, which is good if you want a bigger keyboard, but not so good if you want them to match size when closed together.
I think the Surface Pro is a hidden gem in the computing world. They have a real i5 processor, and are quite powerful little machines, while still being tablet sized. The kickstand is great for watching Netflix in bed (if that’s your kind of thing). They have a full sized USB 3 port, which is also handy. Oh, and 1080p screen resolution, and all day battery power.
That being said, this price for a used machine is well over market value.
