Let's hope this happens for Mac Pro's as well.

Here's the story on AppleInsider...

Apple may be laying the foundation for TRIM support in future Macs, a technology that should allow their solid state flash drives to maintain optimal performance throughout the life span of the systems.

The Mac maker's most recent 13-inch MacBook Pros display an option for TRIM support in their system profilers on SSD-equipped models, one which isn't present in either the second-generation unibody 15-inch MacBook Pros or the latest refresh sporting Intel's Core i5 and Core i7 processors.

Also...

One AppleInsider forum member notes that the same "TRIM Support: No" showed up on his Core 2, 17-Inch MacBook Pro after he updated the firmware on his SSD to version 2CV102HD.

Errrr, isn't that screen the Mac OS showing you the metadata from the device in question. A 'Yes' or 'No' there is a property of the drive; not Mac OS X. If SSDs are going to report TRIM support, that is a far cry from Mac OS X leverage it. This display change just means can read the metadata sent back from the drive. While a necessary "step 0" to a long term solution, it doesn't really mean diddly about actually doing anything with that metadata. For example, is the file system going to do something significant with the model id string?

You are probably correct, but an OSX developer had to interpret a meta data bit and actually give it a label called "Trim support" which implies they are at least aware of this, and presumably doing something to support it, otherwise presenting it would be meaningless.
