I've got a 3-4yr old Logitech wireless mouse/keyboard combo that still works flawlessly (without any lag a human could notice), so I'd be assuming anything recent from them would be much better.
(got it for my PS2 cause god forbid being tethered to that machine.....also got a wireless Logitech PS2 controller also for that, best PS2 controller I ever purchased)
Anyways, as Gabe says, do you really need wireless? I personally can't see the point of it unless you can afford getting rechargable batteries just to rid of the sight of wires, or have a genuine need for it (like my PS2)....
