See, that's the kind of thing that happens to people when a device gets as much TV air time as the Palm Pre, or the iPhone. Peeps get sucked in and ooooh and aaahhhh. Do you recall seeing ANY TV ads for the Touch Pro? Probably not.
People tend to gravitate to whatever gets most heavily promoted, even though there are devices just as good, or better (Touch Pro of course) that are out there. But if they haven't been into a Sprint, Verizon, ATT, etc... store, then they don't even know about it.
Most people want a Touch Pro.... they just don't know it yet.
