First, there are 800000 threads about this already, albeit you did add a poll.
Logging in and out, seriously is it that big of a deal? You actually get to choose what video device to use, and have the option of extending you battery life by doing so. Seems kind of nitpicky to me.
I have now also posted about 5 times about BlueRay, there was no reason to add it. It is, right now, a format that is not doing well at all, comprising less than 8% of the market! It is expensive, and people are not willing to switch right now. Many analysts are predicting BlueRay to not last very long at all, it is certainly not the next DVD. Not to mention that the hardware is very expensive AND it is a Sony product (licensing it from what I have read is very expensive).
Quadcore? Not yet. One of the MBP's design standards is size, and in this size you can't do a Quadcore chip yet, not unless you want it to be: a) heavier, b) much more expensive, c) bigger to control the heat.
There is still a firewire port on the Pro's, just not the regular Macbooks. The loss of the DVI, ok, I will give you that one, I don't get that. BUT, Apple has always been on the forefront of technology, and this is the new way to go, but I think it might have been a little to early.
There are benchmarks on the new 9600m GT, and it does show an improvement. Whether it is enough for someone to upgrade or not is another thing entirely.
Cheaper products: Apple has never been in this market, and, at least in the near future, they aren't worried about entering it. Why would they? Their sales have done nothing but increase for the last 8 quarters or more (see the keynote). And while the global economy is slowing, they have been around for other recessions and have done fine then as well. While at the Apple store the other day (for about 20 min), I saw at least 15 new MB's and MBP's leaving the place, now, I do live in a quite large city, but still, doesn't seem like too much of a slowdown in business to me. Make your own judgements about the price, but Apple has never had low-end stuff, why start now?
