I need t get a wireless mouse for my iMac, which I use as a home theater PC. Basically, my iMac is linked to my HDTV which is in the living room. At this time, I have to stretch to see where my mouse pointer is on the V screen, so I'd like a wireless mouse for that use. It has to work well on different surfaces and have a long autonomy. A nice design would be a plus as well. I don't care about gaming or having several buttons on the mouse. I'd like the mouse to be small and elegant if possible. Thanks for your advices.
