Macworld rumors du jour: external optical drives, multi-touch trackpad

While anything is obviously possible, it sure seems like the safe bet is that Apple will unveil some form of ultraportable laptop at MacWorld in a couple of weeks, and it now looks like the rumor mill is starting to pick up again with even more purported details. This latest round comes to us from the folks at Mac Rumors, who say they've heard "reliable confirmation" about a couple of the new features, including an external optical drive on the aforementioned ultraportable. What's more, they say that Apple will also be introducing "more than one notebook revision," including at least one that will incorporate a multi-touch trackpad. Again, a reasonable bet, but we'll just have to wait until the man himself takes the stage on the 15th to finally put this rumor to rest and gear up for the next.
