Boy do I feel foolish getting an iPhone. If had waited till now on vodafone I could have upgraded to a blackberry storm anything that's got better features and doesn't lack text forwarding, full bluetooth, mms, customizable text alerts. List goes on.
Or you might be missing the point - Apple are slowly building their iphone market by slowly introducing features. After all, the early adopters pay the high price to pay for the future funding of new models. Remember Apple are new to the mobile market so won't rush in and offer the ultimate phone straight away - there is far more at stake e.g. the application store that needs building up which is going to be a big revenue stream for them. They've already just about dominated the music download market so will take their time building up the network for the iphone. Look into "mobileme" and you'll start to understand what they want to do.
BTW, they don't have to offer these features - the iphone will sell regardless as it is a fashionably cool item to have. Just think, if they did offer everything in one go where would the hype, expectation and excitment of launching the next new model be?
