Feedback/opinions on the Surface Type cover?

I purchased the Surface / Touch cover bundle and have been happy overall. However, I got a chance to use the Type cover on a demo Surface at work the other day and found I could type faster. Anyone have any positive / negative feedback on the TC? Not sure I can justify both, but doubt it would bring much on eBay. Although negligible, does the extra thickness feel too clunky to use as the every day cover?
