I'm actually in love with the idea of augmenting humans. In the Matrix, when Neo was first introduced to learning through the Matrix, I was bouncing up and down, saying, "Me next! Me next!"
It was through Doctor Who and the Cybermen that I began thinking about what uses there could be for augmentation that I didn't like the idea of.
But I'd still be first in line.
I think I would want the same as you, @bengy: an augmented reality viewer that takes information from around me, processes it and then feeds it back to me through eyesight. The second, though: I would definitely get a port so that I could learn things the way Neo does in The Matrix.
Oh yes... I think I was right up there thinking that the skills uploading in the Matrix was the best thing ever! I had stopped Doctor Who though, I really should get back to that!
A instantaneous skill learning download port would be completely one of the must have upgrades... assuming your brain doesn't melt down from information overload!
