I set up the surface keyboard and surface mouse with my Lenovo desktop yesterday. They replaced the MS 5050 kb/mouse combo. I miss the palm rest, but key feel is much better. Actually, the best feel I've experienced in a while - easily as satisfying as the old IBM units. A side benefit - the silver/white color contrasts well with the black dust cover on my desk. The palm rest would make me consider the ergo unit but I have never liked the split kb feel - nothing natural or intuitive about it for me.
