Not sure what you're referring to, but, if it's what I think, don't worry about it. Your 17" is a great laptop and will serve you well for a long time - it just came out and isn't going to have a decent update for months. I'm currently mucking around in the basement and posting this on a 1999 G3 "Lombard" PowerBook, so I can attest to the longevity of Mac laptops.
I do recommend a screen/keyboard pad of some sort, either the Screensleeve (which I've seen in use but never owned) or Radtech's ScreenSavrz, of which I won several. The thing that ships with the laptop works but isn't essentially any better than a paper towel.
I also recommend a slipcover to keep off the scratches, like Radtechs, but the Screensleeve seems to do a decent job of protecting the screen and the top (i.e., the most visible part) of the laptop, so it might be a good thing to have. One thing I like about the ScreenSavrz, which might or might not be true of the Screensleeve, is that they're of optical-grade cloth and can be used to clean your screen (and can be washed as well).
