If it were aesthetically pleasing, worked properly, and wasn't much(if at all) more expensive than a normal flash drive of the same capacity, yes. But I wouldn't pay a premium for it and wouldn't use it if it were ugly or bulky.
Good idea though, especially for those of us with portables(i.e. MacBooks with only 2 USB ports). It's just not a luxury that I would pay a serious premium for.
