You also have to consider that Apple will lose more money by replacing the HDD rather than the optical drive. The optical drive easily costs a fraction of the cost it would be for Apple to even include a 256 GB blade SSD. Apple hates making less money.
Apple is going to include the blade SSD one way or the other. So, if it's nixing anything, the ODD is cheaper than the HDD, therefore losing the HDD in that case is far more cost-effective; it also makes sense.
Most people need 512 MiB or more.... Have you noticed that 1 GiB NVIDIA cards are $35 at Newegg? There's a reason for that

.
Yes, it's because they are cheaper to produce. A vast majority of Mac users couldn't give a damn about how much VRAM they have, hell a vast majority of all computer users don't even know what VRAM is! You tell a computer illiterate person buying a 15" MacBook Pro that they're buying a graphics card with less VRAM, than the next one up, they'll say either one of two things; (a) "What's that" or, assuming after you've explained to them what VRAM is, (b) "Oh, I don't do much with graphics." My point is that whether you give them a weaker GPU or less VRAM, it doesn't matter, Apple already has a weaker video option on the lower-end 15" MacBook Pros and a better one on the higher-end one (as well as the 17" MacBook Pro).
Apple customers need to tell the turtlenecked overlord that they'd like a little more "function" in their Apples - even if it means a few mm extra thickness.
Like it'd make a difference. Sadly, there are still far more Apple customers that care about form than function and even if there weren't, Steve-o's ego isn't easily reckoned with. Being in the minority that want the opposite sucks.
Want a quad MBP - can't because of "thin". Want a better GPU - can't because of "thin". Want an actual "pro" laptop - can't because of "thin".
That's basically true of every Mac save for the Mac Pro, which is way more money than I want to spend on my personal computer. Even the iMac is becoming too thin to accommodate as good of a GPU as it should. The best you can do in that thing is an ATI Radeon HD 5750?! Come on! At least a 5770!
Apple has diluted the adjective "Pro" to mean little more than "something shiny to show off at Starbucks". Meanwhile, other vendors are selling quad core laptops with 1 GiB of VRAM, dual spindles + optical, 16 GiB of RAM capacity for less than most MacBook Pros.
Oh sure; Apple is kind of a joke in that regard. Luckily, programs designed to run on Macs still somehow run well on them; the platform isn't so behind its own technology that software is too advanced to run on it. Though it does beg the notion that if you have work programs that are native on Windows and Mac, you'll get a much faster workhorse of a computer with that software for the dollar with a PC.
The MacBook Pros are nice machines, Apple should keep them but add a "MacBook Workstation" line above them - where performance is more important than "thin" and "battery life".
That's essentially what the 17" MacBook Pro is currently, though even those machines are a joke when compared to 17" PC notebooks, that are able to have two hard drives AND a quad-core CPU AND a decent discrete GPU. The 17" MacBook Pro only has half of that at double the cost.
You are my hero.
What's "pro" about lugging around a USB hub?
Trick question!

Yeah, there really is no excuse for there to only be two USB ports on the 11" to 15" machines and three on the 17". THINNOVATION! Haha, thinnovation my arse!
+1

Be lucky if they don't get any thinner
It'd be extremely lucky if they didn't. They inevitably will. The MacBook Air being "The Future of MacBooks" has already dictated us our mobile fate, sadly.
I liked things better when motherboards, video cards and sounds cards were all seperate. That way when one broke you could replace it. Now it's all about integration and when something breaks, you throw it away and buy another.
Ah, the good old days...though the Mac was never stellar about that. Luckily the build-it-yourself PC towers still are, and by that token, so is the Hackintosh as well.
