I intended that kind of option to go into "No, I'll be keeping whatever I have." but I guess it isn't exactly the same as your situation... I don't think I can modify the poll to add an "I'll be upgrading from my iPhone to something else"
It's interesting that 7 out of 7 voters with iPhones prior to the 4 will not be getting the iPhone 4S. Kind of makes sense... We're the bunch who has resisted an upgrade before, and we'll do it again if Apple's upgrade is a half baked iPhone 4S.
No it doesn't make sense. the iPhone 4 itself is a major upgrade from any previous model. The nex model, whatever it's called, will be at least a meaningful upgrade from the 4 and therefore a world of difference from the 3GS, let alone anything before.
