The iPhone was the first touchscreen smart phone to "get it right". I can remember seeing the first unveiling of the iPhone a couple of years ago and it just blew me away with its capabilities (which by the way I still own the 1st gen and no I'm not a MacFanatic). Since then all other vendors have been trying to emulate it. True other phones are catching up, some do things better than the iPhone but overall the iPhone just still has "it". Kind of hard to dispute one million in 3GS sales in its first week. I guess iPhone owners aren't the ones starting debates, they just know they have the better product or bought it for their own personal reasons. It's non-iPhone owners that have to second guess and point out a few of the iPhone flaws to what their winmo phone can or can't do to justify their purchase. Not too many iPhone users out there that need to start a debate to justify their purchase, they just "get it".
Oh, but due to the mac fanatics, I don't take those stats very seriously. They are junkies.
The iPhone appears to be great for the recreational user; for a business phone, I think it lacks dramatically. The thing win-mobile (and Palm for that matter) has is the easy ability to combine the phone with PDA with internet. The iPhone, in my experience, is a lousy PDA, no matter how "cool" it is. But it really wasn't designed to be a PDA, it was designed to meld ipod with phone with portable gaming console.
Give me a stylus; give me a keyboard, anyday. Right now I am now quite there. I have an Omnia, which has a stylus, but only has a virtual keyboard. But in a year, I suspect I'll be where I want to be.
