I really like the MS Natural - its cheap and easily replaceable once the scissor/bubble key decides to get sticky. The layout is very well done and its a whiz to type on. I'm thinking about the Logitech I posted about originally (K860) - but its got scissor/bubble keys just like the MS Natural. RTNGS has a reveiw - which is where I found the answer I was looking for.Wish I knew about this before I got my MS ergonomic keyboard. It's okay, but not wireless. What other keyboards are out there? I know of Kinesis Ergo but can't think of any others. Sorry I can't be of any help.
