I like the idea of the Apple iPhone, I think that anything that pushes innovation in this market space is great.
However the HTC Touch P3450 (Elf) is serious competition for the iPhone mainly because of the interface.
This video from BBC demonstrates the HTC Touch's user interface.
You can order the device today if you wish. Sadly the iPhone is not yet available to purchase in the UK yet but there is massive interest.
Of course the device is a Smartphone running Windows Mobile 6 which means connecting to Exchange to get push email is going to be nice and simple and it will work happily with your Enterprises existing mobile management infrastructure such as the ever popular Sybase iAnywhere Frontline (formally Afaria) and will also run .Net compact applications.
Saying this the Apple iPhone has grabbed the media spot-light and it deserves to but unlike the iPod at it's time of launch there is health alternatives and lets not forget Nokia, Sony Eriksson, LG, Motorola and Samsung they also will have models out soon that will look to combat the threat from Apple. This is all good news for us the customer.
