Have the type 2 cover for the surface pro 2 - ?99 from John Lewis - and yes; i think everyone above have pretty much summed up the device clearly.
The keys are great, and i really appreciate the backlighting. The track pad is rubbish but i have a wireless logitech that i use - your choice on that.
Really, it does come down to what you want, how much you type. Honestly, for me; i use the surface pro 2 like a mini laptop replacer, and i use it to type with, when im out at a cafe or whatever - the type 2 cover is head and shoulders a typing experience above the touch cover. I personally wouldn't even look at the touch cover, if you mainly type. It comes down to what you want to do on this thing. If you're writing a novel, studying and writing thesis papers or doing whatever requiring typing: buy this cover ar whatever price. You owe it to your hands and sanity!
I would say get a power cover, if you can; there are no back lit keys and that could be a deal breaker (it is for me - and i cant understand what they were thinking) but you need to choose.
Go for the type 2
