Just bought a new mouse, as my old Logitech V320 has been playing up for a while. For some reason, it's double clicking on single clicks randomly, jumps about etc, so time for a change.
Looking on ebuyer, I was torn between two:
Logitech MX1100 Wireless Laser Mouse

Or
Logitech VX Revolution Wireless Laser Mouse for Laptops

In the end, I went for the MX1100. Should be here on Thursday.
