Apple should expect an iPhone backlash once the device goes on sale, according to an analyst who has criticised the device's lack of features, price tag and failure to cater for the business market.

In an interview with Macworld UK, Current Analysis analyst Avi Greengart said although the iPhone is "innovative and addictive", he expects "a backlash of sorts as people figure out how much this thing doesn't do".

According to Greengart, there is "absolutely no case for enterprise use of the iPhone" and there are even limitations with the handset that early-adopter consumers will find hard to swallow. The lack of traditional 'hard' buttons could dissuade many from using the device, while the fact that it's not possible to add applications to it may put off others, he said.

Apple has already stated that it will not allow third parties to make software for the device – other than in conjunction with Apple itself. "That means no PDR (Physician's Desk Reference) for doctors, no Weight Watchers for people tracking their 'points', no SlingPlayer for place-shifting your TV, and no Hebrew prayer books or King James' Bibles or Koran readers for the faithful."

Pointing to the applications already available on the iPhone, Greengart added: "Even the apps that are available are not exclusive: Google Maps is also available on the Treo and BlackBerry and Yahoo! Mail is available on pretty much every smartphone."

Furthermore, Greengart said the iPhone's 8GB isn't sufficient for storing multiple films, while the lack of 3G and GPS facilities would also restrict the number of people interested in the device.
