Quoting: Roadkill
Doubt whether these were connected to the PC, though
No, they weren't.
So I've ordered a Microsoft Comfort Desktop 5000 (!!!)
A lot seem to come with the tiny little mice but this one seemed pretty solid looking with a full-sized mouse.
We'll see.
I bought a couple of 1m extension cables, too . . one for the keyboard & mouse and one for my bluetooth thing-ma-jig that I use sometimes for transferring pictures from my phone (it's hidden at the back of the P.C, too so transfer can be slow).
Just hope it arrives for Friday.
