Everybody seems to have an opinion on the potential impact of Apple's iPhone on the mobile phone/device market.
A search for blog posts tagged 'iPhone' on Technorati currently lists over 10,000 items, a considerable amount given that all we know of this phone is the contents of Steve Jobs' presentation, a couple of pages on the Apple website and the opinions of the (very) few journalists who have been allowed a 10 minute examination of the device.
What is clear however is that this is a device which takes messaging seriously. The attention paid to both SMS and Email client indicates that this is a device that people will want to use as a messaging device, a considerable contrast with mobile phones from established phone manufacturers who appear to have added (bad) email clients to their devices as an afterthought.
