IMHO, there is nothing inherently wrong with Apple mice. Take yours to an Apple store to have them test it on their systems (if it is warranty, have them replace it).
Really! Really!! Haven't you seen "Mouse Cursor Disappears":
https://discussions.apple.com/thread/4142250?start=0&tstart=0
75,431 views and 387 replies over 14 months and rising. A similar huge thread on Lion, and rising. There are other problem mouse threads. This has been a persistent problem since the beginning of Lion. I (and others) have had their iMacs examined by Apple's Genius Bar (in my case 5 times plus a change of mouse). About 20 separate solutions have been offerd on these discussions including Adobe's software that changes the cursor shape. No solution (after two years and about 10 updates of OS and none in sight.!) Lots of feedback to Apple's site on this but not a single response, let alone a cure. My Magic Mouse has been a paperweight for months and I am using my 5-year old tethered optical mouse. A huge relief!
But perhaps you are strictly right in saying that there is nothing wrong with the mouse, but who knows, that's part of the problem.
