Why is there different support for different MacBook models?

"13-inch MacBook Pro models from mid-2009 or later, 15-inch and 17-inch MacBook Pro models from late 2007 or later."

Why is the 13" Macbook Pro supported for less time in comparison with the 15" and the 17" models?

Probably due to the integrated graphics processor (IGP), though the late 2008 MBs had the same IGP as the 2009 13" MBP and MB.

PS: Why is this thread titled "Questions." (not very descriptive, but then again) if it is only one question?

Thanks for the reply.

Correct me if I'm wrong, but wasn't 2009 the year the 13" MacBook became a Pro? Late 2008 13" were just aluminum MacBooks. A difference of nomenclature.

You are correct. That late 2008 13 inch unibody was my first Mac. Great machine.

Because mid-2009 was the first time there was a 13" Macbook Pro.

Before that there was the late-2008 13" Aluminum Macbook which was similar minus a few features.

Before that there was only the plastic 13" Macbook.
