I am especially looking forward to no cable and being able to recharge it instead of using batteries like my Magic Trackpad

Also, it's suppose to be wireless which is a joke, you have to have the wire plugged in anyway to charge the non replaceable battery and when you unplug it, it looses connection with the iMac computer.

It is nice that it integrates so well with Mac OS, including showing the remaining battery level, all the keys working as expected, and so on

(I had two actually) and while the solar power worked well enough and I still consider it a great contender, both of my k750's batteries died within 9-10 months-- and replacing their batteries isn't ideal

Great battery life

Works, long battery
