Some of you are trying to fool yourselves into thinking that there really are no differences between a consumer level device vs. a pro device. A pro device caters to and is geared towards a specific purpose taking into account the skill of the user, thus hands over greater control and power to get the job done. Magazine publishers could write their entire works with word but that doesn't make it as professional as Adobe's InDesign which has features designed for the workflow of a professional who will use such an option on the day to day.
Simple, easy to use, not fully featured but hey the consumer won't use those features anyway :
But just because it takes pictures does not make it as robust as one of these:
Whats the difference? Control and ability. You might be able to tweak a few settings on the coolpix here and there, but the pro level option allows knowledgable individuals to do whatever the heck they like with their shots. If you can do your job your job with a coolpix and you get paid for it thats dandy, but I doubt your shots are getting any true play on the photojournalistic circuit. Else there wouldn't be a market for these cameras.
So why do I say the 13" isn't really pro? Too limited, for me, in terms of raw power. Well, to say the least it isn't anywhere near pro compared to the 17". Home users won't and obviously didn't utilize the expresscard slot and Apple for a short time thought FW800 was needless too, because compared to USB it WAS/IS a pro option. Most everything consumer grade can run off of USB, but you don't see any raid enclosures and multi channel audio perhiperals running solely off of USB (with few exceptions) when performance is a factor. With the 17" you can do pretty much anything you want to on the go, with such usability being required for the professional on the go who needs to have robust solutions available anywhere in the world at any time. A macbook (white) can do that, sure, but only to a certain extent.
