Good stuff.

I tried a Logitech MX1000 laser wireless rechargeable mouse for a good 6 months. It was nice and comfortable but the batteries pissed me off, they'd need recharging every 3 or 4 days.

Now im back to corded Razer laser mouse.

I highly recommend the laser powered mice over the optical. I dunno if there are many people who even use the ball mice anymore. Cleaning those things out got so annoying.

We installed several at work and they seem to be holding up fairly well after a year's time.

The firm that built and services of our UNIX system also builds the PC's for us and the latest one in our office came with a wireless mouse and keyboard. They do work really well and the wireless feature is great. I though about swapping it for mine. However, as most of you have seen, oftentimes the wire is what helps me find the mouse on my desk. :o Plus I'm not sure what kind of "Line of Sight" requirements they may have as my desk can get quite mountainous.
