Yes, but it's just as generic as i-anything, which is similar to e-anything. I'm pretty sure "e-phones" could have been a mid-90's spoof name of a pocket-pc. And "pad" was derided as similar to a feminine pad, a much worse link than a trackpad.

The magic was in product and marketing execution, and now i- (and "pad") signifies something more than generic. If HP/Palm pulls this off correctly they could integrate "touch-" into a whole line of WebOS devices that has brand-recognition with consumers.
