I think the 2 earlier comments indicate a trend in computer shopping. How many people do you know that bought the bargain basement Dell, HP, Apple, etc.. WITH-OUT upgrading anything? I bet very Few. I have a feeling that most people see the low end model then decide to add on, no matter what computer they buy. I see the Mac Mini filling 3 slots: a second Mac (for the kids, for the kitchen, a trans-portable one for work and home...) or a second computer for someone getting tired of Windows who is open to playing with a new OS but who doesn't want to get rid of their Windows machine quite yet (or maybe does :) ), or a 1st Comp for someone who doesn't have a computer yet but has family members with Macs for "tech" support (Granparents, etc). I believe that most others will look at a Mac Mini and upgrade to a different machine.
Where Will 900,000 Mac Minis Go?
