USB ports sounds useful.
I bought a replacement MS £7 wired keyboard for my Compaq. I splashed out.
Loss of hotkeys or getting round to remapping is a hassle. So much so I haven't got round to it.
Have tried wireless kbd mice combos before.
Didn't get on with them. Need reconnection all the time. So settled on wired kbd and cheap Logitech wless mouse which always connects automatically.
