I've been using an Apple Magic Trackpad 2 for the past week or so:
- It looks great on a desk, the poorly-lit Wikipedia picture doesn't do it justice. On a light wood desk, in warm light, it looks right at home. It also lines up well with a Magic Keyboard.
As as programmer, I click things a lot. Being able to adjust the click sensitivity is wonderful - I have it turned all the way down, which puts ever so much less stress on my hands:
Note that 'silent clicking' option there - this thing somehow can make noise when you click it beyond the noise generated by the Haptic Feedback thing - I don't know how they managed to hide a speaker in it (I've looked for it), but it's very realistic, rivaling the sound made by my MacBook's physical trackpad.
I have it off because I don't like noise, but it's a neat thing to have.
The rechargeable battery is great, I haven't had to recharge it in the week or so I've had it. It also comes with its own Lightning cable, which you can steal and use to charge other iOS devices.
I don't know what they finished this with, but it feels better than my MacBook trackpad. It seems even less sticky - it might just be that I've worn some of the finish off my older trackpad, but this one definitely feels better.
Doesn't require, or support, a stylus that isn't designed to work with capacitive surfaces, just like an iPhone.
$130 is a little steep, but for using it all day, it's completely worth it. Also comes with a standard 1 year warranty, and, in my experience, Apple means warranty when they say warranty. I've never had trouble getting them to honor one. That said, there's nothing in this to break - something electrical would have to go wrong, as there are no real moving parts. That in itself is a huge plus for me.
