But not on the 15" MacBook Pro that I bought three weeks ago.
Dear Apple: please stop leaving your early adopters out in the cold. I realize you're a company whose purpose is to make money. That's fine, in fact: I can't think of many other companies I'm happier to give my money to. That said, tiny new features like this which you aren't even bragging about on your product sites obviously aren't crucial selling points designed to sell X many more MacBooks and 17" MacBook Pros. They're small but important innovations that all MacBooks to date should have, especially when you consider the fact that right-clicking on a Mac has been a topic of geek controversy since someone first took a side on the Mac vs. PC debate.
Apple, if you're listening (of course, you aren't), please give your early-adopting MacBook Pro buyers (what I'm hoping is) a simple software update so they can right-click with the rest of their MacBook brethren.
