...And what are your reasons for upgrading? The reason I ask is because in the PC world, it's not uncommon for people to still be using Pentium 4 machines. As an example, a lot of companies have been using the bad economy excuse to hold off on upgrading anything these past few years, and yet hardly anybody bats an eye. On the other hand, in the Mac world, telling someone you use a Core 2-era Mac will cause a "what cave have you been living in for the past few years?" kind of look to momentarily flash across their face.
