I have a Mac question of my own:
I am the proud owner of a four year-old iMac. It's by far the best computer I've ever owned. I'm probably going to replace this with a new iMac in the near future. Most of my time on the computer is spent surfing the internet and sending e-mails. I occasionally play games, but it's usually stuff like
Age of Empires (the more graphically intense games are played on my X-Box 360). How much computer do I really need? I know that faster is generally better, but I see no point in spending a whole bunch of money for power I won't use.
