Comparing MB of VRAM is a pretty damn poor way to assess graphics power. The 12" had an nvidea 5200 go and the bigger ones had mobility radeon 9700s. That's a bigger difference than the integrated in the new macbooks and the 9600 the MBP has.
You're also talking about the 1.33 Ghz 15" powerbook, but I'm talking last generation. By that time, the bigger powerbooks had higher resolution and the 12" still had 1024x768. The 15" also had backlit standard by that point.
So you refuse to compare products that at one point in time was out simultanously? Thats like comparing the very neglected Mac Mini (not that I care about that product) to the last iteration of the dual-FW MBPs or the latest iMac.
How is the MBP "not a pro machine?" What would it need to have to be "pro?" I'm sure you're thinking matte screen, but other than that?
Well, the gap has been closed from two ends, not just the MB being upped (and even that "upgrade" is truly an upgrade is debateable). Of course I'm thinking that the glossy-only screens are a downgrade to consumer levels to the extent that the difference is academic only.
Next is the nixing of half of the firewire connections. Yes, it's halfed. And when you begin with two FW ports, that's quite the bummer.
I know they also nixed the only fw port on the MB, but take a look at last generation macbook, and the only real difference I see (apart from some of the things the new setup all received) are backlit keyboards (whoopy) an express slot and a bigger screen. That screen is just a bigger version of the lowest common denominator screen found on all the consumer goods from Apple (i.e. glossy). Further, you don't even have to believe me personally, but go take a look at the keynote, and note how the whole argument is based around catering to the biggest mass: The lowest common denominator consumer.
If you can't see that these downgrades makes it less pro, but more of a yesterday macbook, then I give up. Yes, they tried to keep a big enough gap by also nixing things on the newest MB - downgrading the processor speed, for one - but it doesn't change the fact that the MBP has been dumbed down as well.
