They're not going to be losing any money or marketshare. Apple is entering in as nothing more than a minnow into an ocean. Nokia/Samsung/SE dominate the markets over there, especially nokia. No one is dying for an iPhone there like the sheep over here.
Using the most popular product, because it is the best available, does not make you a sheep. I have 1 ipod, and in the last 6 months have purchased a new Sony , Sandisk as well as a Creative.
The Sony sucks because it forces you to use SonicStage.
The Sandisk has an atrocious interface. The scroll wheel is simply annoying to use.
The creative was nicest of this bunch, but kept crashing and failing.
[I bought a bunch of music players, kept the best, and gave away the rest to friends. Incidentally, the owners of 2 of the 3 music players passed those on, and bought ipods themselves. Again, because they were not using them.]
The ipod does NOT have the most features. It is the MOST expensive. Yet, it is the only one I want to carry with me when I leave home, because using it is not a PITA.
If that makes me a sheep, then so be it. I am a proud sheep at that.
Similarly, the iPhone has a revolutionary interface. If it works as advertised, it will be super easy to use, and the only phone in which you will use most of the features (so while it may have less than others, you will use more. And that is not counting the innumerable web apps that will be created, and the possibility of an API being released in the future).
Agreed, Nokia and SE have great interfaces too. The Sony Ericsson Side wheel was fantastic, however, with the new smartphones, is quite useless. The only way to operate them is using a stylus to press teeny buttons.
And Nokia has just been getting more and more gimmicky (NGage, anyone?). Their latest phones cram too many buttons, which while useful for power users (who are on crackberrys anyways) they are frustrating for regular customers.
The only good hardware maker in phones is O2. Fantastic (and stylish) hardware, but unfortunately they have no control over the software (since they mostly run windows mobile).
So, yeah, the sheep will buy the iphone if it works as advertised, because it will be the best damn phone available for most people. And Apple's whole widget advantage is not going to be stolen very soon.
