I'm surprised your batteries died so quickly, Renegade. I have used an MX Revolution for a couple years and I love it. The batteries last about a week if I don't charge it before then and I typically use it probably 5-6 hours a day.

I also have a VX Revolution I use at work and the batteries in it last several months, using it well over 40 hours a week there and I'm using it constantly when in my office. I think I like the VX model more than any mouse I have ever used and I have used a lot.

I was wanting another VX Revolution since I like it so well so I just bought what appears to be the next generation of it, the Logitech M705 Marathon Mouse. I'm using it on my home desktop now and so far after having it about 4 days I am very pleased with it as well. They advertise that the batteries in it should last 3 years! We'll see about that.

I am particularly fond of the hyper-scrolling on all of the mice I mention above. I loved it from the first day I used the MX Revolution and I think I will regret ever using anything that does not have it now.

I also prefer Logitech models over others I have used. I have used some Microsoft mice but I really prefer the Logitech models over them. I don't think I'd ever be happy going back to a wired mouse since I have used wireless for so long now.

Interesting reading here though on everyone's preferences.

I do LOTS of folder synchronization between numerous machines and USB devices and my tool of choice is Beyond Compare . I also use SyncBack Pro alot but for a fast simple sync of a few folders between two machines or a USB device and a PC, I usually just use Beyond Compare. Works great for me.
