I have both the Edge (Mac edition, of course) and the MX Revolution. Had the mouse for a year and a half now, and it's awesome. Reception is great, buttons are awesome, and battery life is amazing, even though I use it for ~10hrs a day and leave it on while charging. Honestly, if you just put it into the dock when you're not at your computer, you'll never have a problem.
Also, I got it on Amazon for a steal of $49--maybe that is impacting my review, but even if I paid full price, I think I'd still be happy. One thing that does bother me, however, is that I have to leave the dongle plugged in; for the price, it should've been Bluetooth rather than RF.
The Edge is an awesome, awesome, awesome keyboard. No other way to describe it, really. I was hesitant to get it due to a lot of negative reviews and its price tag, but I again found it on Amazon for a huge discount, and decided to make the switch from Apple's wireless Bluetooth keyboard. The typing experience is great--something in between the Apple keyboards and a more traditional Dell-like keyboard--and the Apple-specific keys are a fantastic addition. The trackpad is great for just using as a mouse, but it sucks pretty hard at scrolling around a page. Also, the volume slider works fantastically well (far better than the reviews had indicated), and the lights at power-up are pretty awesome
. I will say that it seems really strange that the iTunes controls on the left go Pause/Play, Previous, and
then Next. I find myself often pushing Previous instead of Next; seems like they should have switched the two.
So, in short, just put the two in their docks when you're away from your desk, and you'll be absolutely fine. I could not be happier with my purchases.
