Aloha:And one more thing from me: Remember Motorola's RAZR? Was a big hype, uh? They sold millions and millions. Everybody loved it everybody wanted it. 2G only, yeah. And then the 3G version was just not the same and the whole phone become some kind of boring after all.
If Apple will not be able to cope with the fast changing technology in the telecom sector (2G, 3G, HSDPA, LTE, 4G...) and come up later with something new, new design, etc then the iPhone will have a similar lifecycle than the RAZR.
The 3G RAZR came a long time after the 2G RAZR, and origionaly the RAZR was very expensive, but within months it was for very cheap, or free with contract. It was a very "in" style of phone at that point, Motorola just milked it waaay too much, releasing inifinite versions and colours with little hardware change, flooding the market. Now everyother manufacturer has a "Thin" lineup of phones matching the RAZR, so there is no reason to buy a RAZR anymore over anything else.
Apple is a little better at keeping on top of things than Motorola, They do not have a iPhone on every carrier and Colour like the RAZR. That should help with the supply vs demand. Hopefully they will always be evolving their design a little how the iPod has progressed.
Unlike Motorola, Apple is usualy able to keep infront of the game, and not let other other players use Apples designs to their advantage(PATENT, PATENT, PATENT)
