Do you find it weird/ difficult when you change your computer mouse?

I've been using only optical USB rodents for my last few replacements...they're easy to replace,being plug and play devices under newer variants of windows..my only problem with mice is, being a lefty,not realising it when I bought it,had a couple of buttons where I would normally grip my mouse...that didn't work out...fortunately,that one seemed to be part lemming,as it kept falling off my desk to the point it broke..it's replacement,still working just fine,doesn't have any extra buttons...but WHY does it need to have a Blue LED that stays on all the time to let me know it's plugged in?! it's like having a blue flashlight..

Yes! I recently got a laptop and a small, cheap mouse for it(can't stand the touchpad...) When I went on the family computer, the size of the old mouse seemed huge!

I changed my mouse about a year ago. I bought a new wireless mouse and keyboard. The mouse just flies along. It is quite large and it took me a long time to get used to it. But now I find it very comfortable to use and I wouldn't ever go back to using an ordinary mouse, that is of course, unless I had to.
