my sisters had a wireless keyboard and mouse . The mouse got smashed . Can she just buy a new mouse, without buying a new mouse/keyboard , keeping the old keyboard or will she have to buy a new mouse/keyboard
You could just buy a new wireless mouse, although it will have it's own transmitter/receiver giving you an extra wire which is against the idea of having wireless inputs in the first place!
Why not check out sites like www.ebuyer.com or www.dabs.com that always have good prices for wireless keyboard/mouse bundles?!
