I used to have a M$ Office Keyboard which was brilliant. Unfortunately the version of Intellitype needed is not Win7 compatible.
I treated myself to a Wireless Desktop 3000 set which also comes in black = mistake.
In subdued light the keys are difficult to read.
Also, being wireless, there are no NumLock, CapsLock or Fkey Lock lights either.
Now considering one of the wired Logitecs with illuminated keys - are they any good?
