IMac – Mouse recommendation for iMac

Your question contains a myriads of questions, but let me try to give you a hint on some.

1. Possibly not, unless you can find a way to fix it, Apple will happily charge you fix it for you.

2. I don't know if it will be better, but I know that the BT on that machine works ok. And that's because I have the exact same model. Mac Pro early 2008 with Dual Quad-Core Xeons in it.

3. Yes and no. I've used the (included) Mighty mouse for a week. I hated it and simply gave it to a friend who liked it. There IS some latency in BT peripherals and there are some micro-disconnections that get fixed real fast, but if you're playing a FPS, you'll notice a small "it's not working" moment. Also, the less change the batteries have, the more this will happen. Same with the keyboard. You're typing and then ……… a couple of secs of nothing and then it works again. Sometimes you even get the "Disconnected" Bezel on screen.

4. I can't help you with that. I absolutely hate mighty mice.

_{The plural of mouse is mice ;-)}

I've used the RadTech BT500 for some time and love it. It's small, rechargeable, works well, and silver in color, to look good next to aluminum Macs.
