yeah. i think it helped that the 12" powerbook's (my fist mac) build quality and aluminum frame were years ahead of the competition. but, i wouldn't have taken the plunge and a loan to get it if it wasn't for final cut pro. it was an investment, which hasn't paid of yet personally, but, an investment that paid off by choosing apple because of the improvements of os x over the years and the quality softwares apple has churned out (final cut express, itunes, garageband, etc.) soon there after. of course, a lot of people feel that apple is behind the times in their pro apps, but, there is supposedly an update coming in may to final cut studio and i hope, final cut express, too. my wish list for these updated pro apps is, of course, optimization that will utilize open cl, grand central, 64-bit, native avchd editing, etc.
ps--recently updated my 12" powerbook with an i7 15" mbp. i did look at pc laptops before deciding that a mbp is what i was familiar with and again, the look and feel of the mbp, although not the deciding factor, helped.
pss--actually, now that i think about it, the powerbook did pay off, but, not what i expected. in one of my tv jobs, we needed to use our own laptops and they preferred a mac laptop, in which i got paid extra money (a rental fee for the laptop) added into my weekly check. it wasn't what i expected because it was an office job using ms office and photoshop, instead of video editing, which the powerbook could still do given plenty of render time and exclude hi-def video.
