I use bluetooth constantly on my pc (unfortunately not for input devices) but never noticed this "delay" try this site and forum for any more data you need to solve bluetooth problems, it helped me a lot Jons Guides however buying a new keyboard and mouse I would get a BT one so I'll use one single dongle to connect all my stuff: pocketpc, modem-phone, earphones, keyb and mice, without having hundreds of transmitters on the desk....
