I need a wired USB keyboard with higher keys for my iMac. I don't like the flat keys plus many of them are so worn that the letters are illegible. Are the older-type keyboards still available?
Logitech and Microsoft both sell USB keyboards that work great... i think when you plug in a non Mac USB keyboard the OS asks you to identify the , option and control (?) keys, so any USB keyboard will work
Personally, I like the wired keyboard that Apple is selling now. It feels and looks great, even though I didn't think it would have enough movement for me. But if you're sure you want something else, and are willing to invest a bit, Matias makes a replica of the keyboard that used to come with iMacs, and it looks much better than most of the third party keyboards you're going to find. Plus it comes with all the Mac keys by default. It's got the USB hub and everything.
