MacBook Pro - 17" vs. 15"

[M A V I C]

[quote St. Bernard]I'd say it largely comes down to where you think you're going to use it. If you need something really on the go (to quickly check/send email or calendar), a BlackBerry or iPhone may be more useful. If you're cranking on planes, you may want to just stick with the 12" (even *that* can be too big). If you're looking for a mobile office, I'd go with the 17" myself.
I already have moto Q (WM5) for email and such. I should probably explain more what I'll use it for...

Mainly on photo shoots. About once a month I fly to a photo shoot where I take a ton of pictures, create a slideshow, then a gallery and burn that to about 100-200 discs, then I fly back.

One of the last shoots I did I filled up my 60GB HD and the PB slowed to a crawl. Plus, the galleries are getting so huge they take hours to build so HD size is important (the less full they are, the faster they are.) Also, when I burn the discs I currently have four external burners but can only use 3. That's because I only have 2 USB and 1 FW port. So if I had the 17", I'd have the extra port and could then cut my burn time down by a quarter. It currently takes about six hours to build the galleries and another six hours to burn discs.
