Just got my Magic Keyboard and Trackpad II from UPS and I already love both peripherals. I find that I type better with the new keyboard and the new trackpad is much better.
I picked up both as well... I had pre-ordered the keyboard and mouse for store pickup and was listening to the latest Daring Fireball on the way to the Apple Store... That episode was talking about the new trackpad and they convinced me that trackpads are better than mice! $129 better?
I've had them both for about a day and here are my thoughts (FYI - I'm also a big mechanical keyboard fan, and also use my Pok3r with Cherry MX-Brown keys).
- Both devices - seem really responsive. Much more so than the legacy Apple keyboard and mouse. I'm not sure if that's true of any BT4 device, but they feel "snappy".
- Trackpad - wow... Expensive. But I like it... It can do much more than a mouse and the force-click is promising - just not very useful at this point. As soon as I saw the trackpad sitting on the counter, I wanted it.
- Keyboard: again, as a mechanical keyboard user, I kind of thought the key travel would be underwhelming, but it feels great. I'm not sure what's in the switches but they definitely pack a punch on the way back up - more so than the laptop keyboards and older BT keyboards. I'd liken them to MX-Black switches with little travel. I kind of feel like the smaller the travel, the more activation force you want. Reviews had said these would take a long time to get used to - I feel just the opposite. I feel comfortable with it right out of the gate.
Regarding cost... This would be true with any rechargeable item - but you figure you're throwing away batteries every month or so (two for a mouse, three for my old keyboard) - it adds up! I'm sure I've gotten 10 or 20 40-packs of AA Duracell batteries over the years and that's something to consider.
