The difference in computer tech. today compared to 5 years ago ( G4 chips) is a gigantic difference. So how long will a Core 2 Duo Laptop that you buy today last? Will it last the same amount of time as the G4/G5 chip computer? Since tech. is always changing and getting better is it only expected to have a certain life span or have we gotten to a state where technology will last longer since its so advanced?
