Query: It's Love & Hate; but Love wins!

I've been using this model of mouse with my desktop computer since 2005. I've tried to stray to other models, but it has never worked out. The 5000 (aka IntelliMouse 2.0) feels like an extension of my biology. The full-size and right-hand orientation just fits me perfectly, which is more important than any of the bad stuff.The scroll wheel does fail, pretty much invariably between 8 and 14 months. The RF receiver is huge, so mobile use is not ideal. The buttons can fail, though the wheel is more likely to go first. Battery life is good, even if left idling all the time.So, my solution to the problems is to keep spares on hand. This is not an expensive mouse. I've gone through 8 units in 7 years, so the cost is negligible. My only concern now, in 2012, is that it appears that this model has been out of production for at least 2 years now. So, all that is left is closeout and old stock. I may have to say goodbye soon, but I prefer not to think about it.
