I find that, as a general rule, the really famous bands usually have simpler names, whereas local bands go with more interesting, funny, or bizarre monikers. I've always kinda taken that to mean that the band, not the name, ought to be the grabber. I'd also venture to guess that a a simpler name is easier to remember...a quality which may be more important enough to give it an edge over a name which is intriguing, but odd.
With that in mind, I think "Portable" is the best of the bunch.
