I use a Logitech MediaPlay myself, and have done since day1 of release. On my 2nd now, although they're harder to find replacements of on eBay etc now due to their age. Although designed as a "media player remote"/mouse combo, I have at the end of the day 17 buttons on it I can use (Only use the base 5 and vertical scroll though for day to day). Mainly use it due to it's shape, I've not found anything as comfortable in a long time - The old logitech Pilot corded mouse (3button scroller) came close though.
