My aim regarding the purchase of a MacBook Pro is the portability/power ratio. Since I will be replacing a powerful computer, I still want to play something now and then, so that is why a 17" display is the chosen one.

I don't like the MacBook and MacBook Air. For me, the price/power for those notebooks is not realistic. Especially for the MacBook Air. It might be really portable and stuff, but power is compromised to the hilt.

The reason I want Macs for notebooks is that AFAIK, the software problems aren't a weekly issue like with Windows, and it really is a good work horse plus it has some nice things added like a music maker which I intend to use.

EDIT

My purchase will be in the summer. I do not wish to change my computer now.
