I used to have a Rev A 12" Powerbook and loved how "portable" it was, however the speed was disapointing and to cut a long story short I sold the powerbook. I bought beacuse it was (and still is) better than any similar sized PC laptop out there (I own a PC desktop too). Now with the Rev C powerbooks out there I am considering getting another. At first I thought that I would get another 12" powerbook, however the 15" ones are now Aluminium (still Titatanium when I got my Rev A 12") and the 17" is very reasonably priced - I'm also thinking desktop replacement! So now the question: I'm looking for views from 15" and 17" owners on how "portable" their portable is ? A 17" could be used standalone and replace my PC and be portable ; the other two may need monitors when I'm back home. But if the 15" and/or 17" is too much to carry from one location to another I may have to rethink my plans. In addition to larger screens the 15" (1.5Ghz) and 17" are a bit faster have better graphics as well as FW800, PC-Card slot and better memory configurations so would be more suitable as desktop replacements. Whatever laptop I go for, extra memory (Crucial), 5200RPM 80GB hard disk and Superdrive will be fitted. Sorry for the long winded question, I hope I didn't bore anyone and I look forward to your responses.
