Wireless keyboards and mice.

[kaiowas]

Anyone here know much about how these work?

I've had a logitech MX610 wireless left handed mouse for a while and I've carried on using it with my new laptop as I find it much nicer to use than the trackpad, i'm now also thinking of getting a wireless keyboard to give me the ability to use a full keyboard on the occasions when it is preferable to do so however for ease of use I'd like to only use the 1 wireless dongle for both, is this possible?

On the one hand I've got the idea in my head that the dongle needs to be in some way coded to the device it's supplied with otherwise in a busy office where more than one person are using wireless you'd all end up controlling each others computers but on the other hand this would be a nightmare from a manufacturing and support point of view so it might be possible to either repair the devices or to mix and match.

Anyone know enough to give any useful advice? My laptop has bluetooth so it might be that I have to go that way but they tend to be expensive for something that would only be used occasionally.
