That would be perfect; their current wireless keyboard is too laptop-like. I like having wide arrow keys, the delete/end/page up/page down/home keys.
Otherwise, can someone recommend a similar option?
Agree with Loïc that this question should be rephrased, but if you're looking for a possible solution without being subject to Apple's whims, there are many third-party bluetooth keypads available...
Speculating on when Apple will release something is pointless, but here's a nice-looking alternative:
I have this one. It has the command key instead of the windows key you'll find most of the time.
It's been discontinued but I still see it regularly at the local Futureshop and Best Buy here in Sherbrooke, QC Canada.
