Well, some GREAT technical help you got here, bro

Unfortunately, I'm no expert on cordless keyboards and mice either, for the precise reason that they're extremely annoying cos you need batteries! What's the problem with cords anyway, as long as they're long enough?
Anyway, I had a look at that site you linked. All the features are listed, all you have to do is compare them - the features are all described in the list on the right. For example, the only difference between the top two is the top one has a "detached Media pad" - sounds like a load of bollocks to me - why do you want your keypad seperate with media player controls? That just makes your software interfaces obsolete in the programs. A lot of useless fluff if you ask me.
All the info is there, you just need someone to interpret it for you? Or are you just lazy?
USB, PS/2 means how the transceiver connects to your PC.
Bluetooth is how the higher-end ones communicate with the transceiver. Bluetooth is a short-range 2.4GHz band RF comms system. Others connect by other RF - it doesn't matter as long as it's RF i.e. not line-of-sight like infra-red.
Optical mice (I DO have one of these

) are obviously much better than ball-mice, that's what the "optical" refers to.
Whether the mouse is rechargable or not could be important: rechargable is cool until the battery dies then you have to shell out cos it's proprietory - unless it uses an AA battery pack or something standard.
All the rest of the stuff is just like internet forward/backward buttons etc.- quite nice to have on the mouse, but pointless on the keyboard since backspace etc. does this already. Programmable buttons on mice are nice - unlike Aelia, I find them really useful - I have the MS Optical Intellimouse Explorer - expensive but very good mouse.
In general, MS and Logitech are both good for mice, dunno about keyboards.
Is this helping??
