Just to remind everyone (who says I take these things too seriously

) this isn't urlwolf's personal machine. It's work supplied and, I presume, what he uses at work. I'm with renegade and others on this: if it were me and we were discussing my home computer I'd be a lot more leery unless the machine to be supplied were very high spec.
I note that in Canada Mac prices have remained static while windows based computers have plummeted in price. Thus, the Vista notebook I bought for $749 a month ago has specs that I would be spending at least $1000 more for in a Mac notebook (512 MB dedicated video card, Intel Core 2 Duo processor, 3GB RAM, 250GB HD, 15.4" trubrite screen, HDMI, etc.). A lower spec'd 13.3" iBook is $1200, larger screened iBooks/Powerbooks are more expensive and my estimate is thus likely conservative...
EDIT: clarified the last sentence and would like to add that I went looking for Mac notebooks online in Canada and they range from $1050 for a base 13.3" iBook to $2800 for a 17" Powerbook with specs similar to my PC notebook (albeit with a higher spec CPU).
