I've got a 17" MBP (with a 100g HD) that I use for video editing, as well as emailing, iCal (work related stuff). I've also got an iBook that I love for doing my creative writing. But the iBook is on the fritz and I'm considering whether to get a MacBook to replace it. I could do my creative writing on my 17" MBP, but I don't like all that excess size, nor do I like the keyboard as much for writing. I'm also thinking of shoving my iTunes and iPhotos stuff to the MacBook (if I got one), to free up some HD space on the MBP. Then there is also the value of the laptop if stolen. I'm sure a lot of people out there would love to have just one current laptop, but are there others out there who use more than one laptop - say one for editing and one for writing? BTW - a 15" MBP would seem overkill to get if I've already got the 17".
