Actually, completely unimportant, but I would be interested: how old is your PC / laptop?
Purchased mid-2011 (imac), 3 years ago restored to factory settings, runs perfectly, super device
My PC is about 8 years old and runs fine. My pad is about 4 years old and runs fine.
Laptop 3 years
Mac 2 years, but the e-Mac from 2003 is still synonymous (only the Mac in between had flabbergasted after a few years)
My main PC is basically about half a year old. But I have gradually upgraded or retrofitted.
I also have a MacBook Pro Late 2011. That explains the whole thing by itself xD
A survey would be useful here.
My laptop is 3 years old.
