Looking at getting a wireless mighty mouse and just looking for some feedback from anyone who currently has one or has had one and got rid of it. Pros, cons?? Also, what is the life of a wireless mouse like that b/c i had a wireless mouse for my pc about a year ago and it died after like 7 months. It wasnt a bluetooth mouse and i dont know if they are different from just 'wireless' mice but i think its pretty pointless to spend $80 on a mouse if it is only going to die after a few months
