After deliberating between 12" and 15" for a week, I recently ordered a 12" powerbook with the 5400rpm drive option. I decided on the 12" for a variety of reasons: (a) I will be taking it out with me every day, often while biking; (b) I like things light; (c) I've been using my trusty G3 600 for three years, and it's my favorite mac yet, since 1989); (d) It seemed less fragile than the 15" due to its shorter size and extra width; (e) sounds like battery life is dramatically better, and (e) With the money I saved, I would be able to buy the Production Suite - Final Cut Pro, DVD Studio Pro, etc. I work as a composer and video artist, so I do a lot of work in Max/MSP/Jitter, Final Cut Pro and Digital Performer. I wanted to get this laptop now because I have an upcoming production for which I simply can't use my ibook (not enough horsepower). In the three days since I've ordered it, I've begun to feel that I may have made the wrong decision. I will still be carrying it around everywhere and want something tough (I don't think either will be as rugged as my ibook), but I've discovered that I can get the software for free through work; and my parents, who know I'm low on money, gave me a dramatic gift and told me to buy whichever computer I needed and not to cut corners... to really get what I need. I've also been borrowing a TiBook for the last week and have gotten used to its screen. Part of my equation in buying it was that I know that some dramatic chip change is probably in store next year - G5 or dual G4 or something! Unfortunately, I really need this computer now. I figured it was better to buy slightly low end and then if I really wanted the 15" to get it in the new chipset in a year's time. The 12" shipped yesterday. It seems as if it is not returnable as I got the 5400 drive; is that correct? Is anyone successfully using the 12" for audio/video production? I'm more worried about the real estate for FCP and DP4 than Max. I don't want to be disappointed in this computer - I want to be really into it. Maybe you just get used to whatever screen you're using a lot. Probably if I'd gotten the 15" I'd be worrying that it was too big, bulky and fragile! As a side note, although OS X rocks, I feel a bit nostalgic and sad selling off my last OS9 computer! I've been using this OS for almost twenty years!
