::Edit:: (Gears in brain start spinning) But, what if I were to take the iPod into an Apple Store later in the afternoon (1 hour or so before closing). I tell them that it only holds a 4-5 hr. charge. (Only fear I have is that they ask how has it been happening, do I say, "Since I got it" or "Just in the past few days") Since I'm there at the store, would they carry batteries right there and fix it on the spot, or just pull a new color off the shelf?
As fabulous as that would be, I don't know if it would work. Before they can go ahead and replace anything, they'll keep your iPod overnight for a battery test. If it fails, which it sounds like yours will, it'll probably take another day or so to get the replacement. I don't think they do in-store battery repairs (or really any hardware repairs for that matter) and the unit that I received, though new and spiffy, didn't come right off the shelf. In fact, it didn't come in any packaging except the plastic sheet that protects it from smudges and scratches.
Oh, and I don't know how long I would wait. I think that the chances of you getting a new model iPod while your model is still in the current generation is kinda slim. If you can still order 3G iPods off the Apple website, I doubt they're going to run out of your model anytime soon.
If the battery thing is bugging you at all, I'd say go do it now. Plus it gives you more time under warranty if your new battery fails, even though it's guaranteed for 90 days after you get the replacement or until AppleCare expires.
