Enermax Aurora Micro Wireless
I quite like this little guy. Its pretty comfortable, its got a nice fat enter key, the layout is easy for those of us with smaller digits and its got a nice, high DPI rollerball for mouse control. The media keys are also pretty fully featured with easy to reach function keys. The only real problem for me was the large price tag; that and the fact that the rollerball goes crazy if you move it really fast.
There are much cheaper ones out there, and in reality I’d have expected higher quality switches for this price, but if you can afford it you’d probably like this one.
