Quite a strange statement. Have you read about well documented issues with iPad WiFi, iPhone WiFi, screwed up WiFi N antennas in Airports? Besides, Apple contibutes very little to wireless technologies in general. It just uses exactly the same components that all PC manufacturers do. And you should be the only person in the world who experienced any issues with wired mice. Even the $5 ones "just work". Magic mouse on the other hand... Here is what one fellow MacRumorer wrote: "
I have a 27 inch IMAC and having a problem with the Magic Mouse. Sometimes it has a mind of its own and starts scrolling without any finger motion from me. The navigation feature (forward and back) doesn't work worth a darn. I usually have to do the two finger swipe left and right several times and sometimes up to five for any response on the screen. Anybody have similar issues or any ideas."
