I am trying to help my office choose between two different wireless keyboard and optical mouse combos. One option is the Microsoft optical desktop 1000 for .99. The other option is the Logitech wireless mouse and keyboard EX110 for .99. Which one of these combos would you purchase if this is all you had to choose from?

I am experiencing extreme shoulder and upper back pain from using my mouse. This has lasted 5 years. I get physical therapy, I feel better, but when I use a computer mouse I experience extreme muscle spasms and strains in my shoulder. What ergonomic device should I buy that would ease the strain on my shoulder, back and arm? I bought an adjustable armrest but that just causes the pectoral in my chest to be irritated.

I want to buy a good wireless mouse, and i saw there are laser ones and optical ones. What’s the difference between them and which one is better?

I’ve recently been getting severe hip pain from my desk chair (I’m a sysadmin and sit a lot!). I’m considering going to my doctor to ask this question but I don’t want a blank stare of "you’re a moron" if it’s not possible. Thanks!
Thanks guys both answers are great but I’m still a yahoo answers n00b so I can’t give you credit…. Thanks again!

I have a wireless optical mouse with no name that I cant set up on my computer. It says that the usb is an unrecognized device. How do i fix this and use the wireless mouse?

And please don’t tell me Office Depot, Office Max, Fry’s, Best Buy,Target, etc. Been there, done that. I imagine that there must be an independent furniture store somewhere that carries this type of item, or at least can special order out of a catalogue. I am looking for something that is tall, but narrow, like computer table with a hutch or shelves above the monitor area no more than 35" wide.

I want to know what should the dimensons be for the computer desk- height,length & depth of desk.Width & depth & ht of keyboard tray.Height& depth of chair.

I got a Microsoft Optical Mouse 2.0 with a usb optical receiver and a USB keyboard.. Will they work with PS3 OS or Yellow Dog Operating System in PS3?
