Since it appears that Logitech has discontinued their Mac keyboard, I don't know of any other options for keyboards that have inbuilt controls for the brightness and other functions for an Apple portable. For my new MacBook Pro, I'm looking into purchasing an mStand, a bluetooth keyboard, and possibly a bluetooth mouse although I may continue to use the RF Logitech mouse that I already own. I don't like the limited travel of the keys on Apple's latest keyboards and would like an aftermarket keyboard if such a beast exists. I don't want to buy a discontinued/unsupported product as incompatibilities could arise in the future, and I'd like to keep whatever keyboard I end up buying for at least 5 years.
