The whole point of Thunderbolt is to take advantage of existing Mini Displayport to eliminate need for an extra port. Therefore I don't see losing.another port or backlit keyboard as likely due to it.
The thing that concerns me is logic board space of another chip. If I could have a discrete GPU or TB, I would go with the GPU. I think this is a big concern that Apple found space for TB yet let its Pro 13" users with a lack of real graphics capabilities. I like TB but I don't understand how Apple decides how to place value on space. Why get rid of backlit keyboards on MBA? Why not give users a discrete GPU in 13" MBP? Why not eliminate optical drives when they waste so much space.
I just don't get the decision to find space for TB but not find anything better than Intel's non graphics solution with its poor performing IGP. I love TB and all of the capabilities it brings but I don't understand Apple's decisions on how and why to use space as a whole particularly in the 13" MBP line. That affects the 13" MBA as in the past all 13" models followed the same path in terms of GPU and chipset. The future looks bleak and I don't understand the decisions that gave us the current 13" MBP.
The only notebook that Steve Jobs (aka Apple) is interested in at the moment are the Macbook Airs ... Why? Because Apple (Steve) did a keynote on them and Apple did advertising on the Airs .... You know when Apple (Steve) loves a product because they run ads on them ... The MacBook Pros are not on steves radar of importance (Haven't seen a Pro ad in awhile) ... Its all about thin and light and the iPhone, iPad, and MacBook Air fit that category .... Listen to what Steve said about the Airs, "The Future of Notebooks" and "The Future of Macbooks".
The 13" MBP is a prime example of what apple thinks about that line of "pro" notebooks (the 11"air has a better resolution the the 13" pro) talk about a slap in the face .... When was the last time Apple held a keynote on the MBP's ?? WWDC09, Apple at the moment cares about thin and light and us air owners should be glad about that.
The Pro updates were half assed in my opinion. Especially the 13" Model.
Apple should have done the following:
13" Notebooks are only Airs
Get rid of the white macbook and 13" Pro
The 11" air is the "new" entry Mac.
The 15" Models come in 2 configs 512MB VRAM and a 1GB VRAM. Hi-Rez screen standard now in either glossy or anti-glare. Standard 7200rpm 750 GB drives with the remaining options being SSD's. Obviously 4GB Ram Standard, and you can keep the SB Processors.
The usual I/O (ie: Thunderbolt, USB, Firewire).
Apple is screwing the pro market notebook user. But I'm an Air user (Ultimate) so yea.
