Yeah, the whole 2G = 2nd Generation thing is getting old. Most people with any sense can discern 2G from 2GB, but that's assuming that most people
have any sense, which sadly isn't the case.
(I don't get it; when people say they have a 120 Gigabyte Hard Drive in their computer, they always say "120GB," not "120G." So why get confused at "2G iPod?" It's simply confounding!)
Even with clarification, people still foul it up. I concur with recommending to referring to it as the G2 Shuffle, or even "new iPod shuffle" as Apple refers to it on their site.
I'd recommend naming it "clippy" but well... that would just start a whole new debacle!
Anyway, even though I already have a 5G iPod (err... that's 5th Generation, or G5, or iPod Video) I might pick up one of these clippy ones. I could take it places where I fear to carry my larger & more expensive iPod. It would also make a great gift!
