"since apple sold 1,000,000 iphones in a week in the US only, i would not worry that much for their market shares."
1 million is nothing in the phone world, Nokia alone sells 1 million phones every single day. Even that is only about 30% of the total market.
It's also deceptive to look at launch figures for a hyped up device as it is bound to be bought by the hardcore of fans for the first week or two. After that it has to rely on the average consumer to survive, and as Sony found out with the PS3 that's by no means guaranteed.
But I think you're missing the point about what I was trying to say: the market for a $600 on-contract phone just isn't that big.
The average contract phone is free (some of them even less than free if they involve a rebate), and even if you look at sim-free prices the average amount people are prepared to pay is about $100. Very very few people are prepared to sign a 2 year contract that costs about $1500 in total, and then pay $600 on top of that, purely to use a phone.
If Apple is serious about market share as opposed to profits, then they'll have to bring out some extremely basic, cheap models, simply because that's where almost all the sales are.
"symbian look to me very ridiculously non-user friendly and unstable."
Have you actually tried any new Symbians lately? S60 3rd Edition is extremely stable, crashes are very rare (on all but one S60 3rd models I've tried I haven't had a single crash).
As for user-friendliness, you can't do most of a S60 phone's functions on an iPhone. No third party apps, no broadband access, no videophone, no MMS etc. It's also not very user-friendly if you want to use it with one hand, as most people do.
