Thunderbolt connector
Apple shows off its '11 MacBook Pro notebooks

Apple today released a revamped MacBook Pro lineup. Those expecting fresh new case designs and SSD boot drives will be disappointed.

The smallest member of the MacBook Pro lineup, the 13" model, is finally moving into the modern era by ditching its base Core 2 Duo processor for a Core i5 processor running at 2.3GHz. Standard storage capacity has been bumped from 250GB to 320GB and the standard 4GB of DDR3 memory is now running at 1333MHz. 

While the sleek 13" MacBook Air is sporting a 1400x900 display, the 13" MacBook Pro still soldiers on with a 1280x800 display. When it comes to graphics, Apple has ditched the NVIDIA GeForce discrete graphics for the on-chip Intel HD 3000 graphs solution with 384MB of shared memory. 

Other features worth noting are FaceTime HD (triple the resolution of the previous FaceTime camera), support for SDXC memory cards, and an implementation of Intel's Light Peak that it dubs "Thunderbolt". 

“Thunderbolt is a revolutionary new I/O technology that delivers an amazing 10 gigabits per second and can support every important I/O standard which is ideal for the new MacBook Pro," said Philip Schiller, Apple’s senior vice president of Worldwide Product Marketing.

Apple further describes ThunderBolt:

Thunderbolt enables expandability never before possible on a notebook computer. Featuring two bi-directional channels with transfer speeds up to an amazing 10Gbps each, Thunderbolt delivers PCI Express directly to external high performance peripherals such as RAID arrays, and can support FireWire and USB consumer devices and Gigabit Ethernet networks via adapters. Thunderbolt also supports DisplayPort for high resolution displays and works with existing adapters for HDMI, DVI and VGA displays. Freely available for implementation on systems, cables and devices, Thunderbolt technology is expected to be widely adopted as a new standard for high performance I/O.

The 15" and 17" MacBook Pros also get processors upgrades, and both are now available with quad-core Core i7 processors (2.0GHz in the 15" model, 2.3GHz in the 17" model). Like their little 13" brother, the 15" and 17" MacBook Pros also gain SDXC slots and Thunderbolt. Standard storage on the 15” and 17” MacBook Pros are 500GB and 750GB respectively. 

The biggest news for the two largest members of the MacBook Pro family is the removal of NVIDIA discrete GPUs to accommodate new AMD Radeon graphics. The 15" model comes packing a standard Radeon HD 6490M with 256MB of memory while the 17" is equipped with a Radeon 6750M with 1GB of memory.

As is typically the case with Apple's notebooks, the latest MacBook Pros will cost you quite a bit more than comparable Windows 7-based machines. The 13" MacBook Pro still starts at $1,199 -- Apple also offers a 13" MacBook Pro with a 2.7GHz Core i7 processor and 500GB HDD for $1,499. The 15" MacBook Pro starts at $1,799 and the 17" MacBook Pro starts at $2,499.

The new MacBooks come with two USB ports and the new Thunderbolt port.
Lets be more specific, its going to come with the new Thuderbolt port and two USB 2.0 ports.

What kills me is that Apple is most likely not going to support USB3.0, thats the problem, and this is clearly a case of Apple going against an open standard.

USB 3 can achieve ~5Gbps (half of theoretical speed of lightpath) speeds which is more than enough for pretty much anything but display uses, but will be far superior in terms of powering devices and even sports an increased power draw over USB 2.

So there is clearly a problem here if Apple decides not to support USB three.

Technologies such as fiber are clearly the future, but that does not mean you can forgo the present. I welcome change, but forcing something upon users is not a good way to do business, regardless of your feelings. USB is everywhere, so its not like manufacturers are going to be switching overnight, its going to take years. Does that mean Apple users will be left out of using newer USB3 devices which manufacturers will surely continue to support over LightPath for some time.

So the question is, Will Apple support USB3? If not there is clearly a problem which you cannot ignore.

P.S And I'm not even going to go into the power scenario, USB3 will support much higher draws than USB2, so if manufacturers start making use of this, Apple users may be left out in the cold.

No, it's entirely likely that Apple will support USB 3.0.

It doesn't now because there's no official controller chipset from Intel; you pretty much have to talk to NEC to get one. And right now, most systems with USB 3.0 are only using it on one or two ports, and never all of them. Apple probably doesn't want to have to label ports separately or have users decide which one device is important enough to get the fastest connection.

If I remember correctly, it might not be until Ivy Bridge (early 2012) that Intel has official support, and that's when Apple is most likely to make the jump.

So I take it you were adamantly against Apple when they dropped Apple proprietary interconnects (Apple Desktop Bus) and old, slow serial busses (RS-232 and RS-422) when they launched the iMac and only supported USB? Apple was "forcing" people to move to a newer, more universal interconnect system. From what you are saying that was an evil thing to have done. RS-232 was everywhere, RS-422 was common, for Apple users Apple Desktop Bus was the "standard". It has taken a long time for the world to move to a USB standard. Hell, you can still buy brand new motherboards today that support the old keyboard/mouse interconnects! So Apple moving to USB in the late '90s was truly a bad thing to do.

Lightpeak (aka Thunderbolt in Apple parlance) supports the USB 3 protocol over the Lightpeak physical media.

How is any of this rant Apples to Apples..

I don't see how anyone can argue that replacing multiple interconnects with a single standard is a bad thing. That said this is clearly not a fair comparison to what is being discussed.

LightPeak can't replace USB for everything, so its not going away. Merely making it a legacy connection and not attempting to improve upon it when it is the industry standard for pretty much anything is incomprehensible in my opinion.

Of course I'm making predictions here, Apple could very well implement USB3 in which all of what I said is a non issue. Its my opinion that LightPeak should complement USB3, not replace it. (and from what I've gathered, this seems to be Intel's position as well.)

I just have a bad feeling Apple won't follow this path, heck if it were up to Apple we would all be using firewire instead of USB. Alas USB became the standard and Apple had little choice but to implement it. Seems eerily similar, don't you think?

As I said, technologies such as LightPath are the future, but USB3 is the present and cannot be ignored.
