I've been a big fan of Logitech cordless. My previous one lasted at least 8 years! However my almost year old Logitech Performance Mouse is having a bit of a aneurysm? I've got a Customer Support ticket running on it. But up and until now it has been all I needed.
On another point, be warned about Graphic tablets. My one, which has been as good as gold, has given VP11 b683 the heebie jeebies. I've disconnected it.
