In summary, the iPhone raises the bar for all other smart phones. The battery lifetime turned out to be better than Apple's claim of a maximum of eight hours, as he could get 7h18' of talk time while Wi-Fi and email fetching was on. The touch-screen interface and glass display was easy to use while scratch-proof. The iPhone does not feature SIM card, which one side gives Apple and AT&T a huge control over the phone, but it also makes the iPhone a no-target for thief as one would not be able to activate a new account. While the iPhone features a 2-megapixel camera, it can only take photo and it can not record video. The virtual keyboard requires some training but at the end it is rather quick for entering text; however you have to switch to a different keyboard view to insert a period or comma.
As mentioned by the Walter Mossberg:"Expectations for the iPhone have been so high that it can't possibly meet them all". So one will find some drawbacks or missing features, hereafter are those identified by the WSJ columnist:
The iPhone is missing some features common on some competitors. There's no instant messaging, only standard text messaging. While its two-megapixel camera took excellent pictures in our tests, it can't record video. Its otherwise excellent Web browser can't fully utilize some Web sites, because it doesn't yet support Adobe's Flash technology. Although the phone contains a complete iPod, you can't use your songs as ringtones. There aren't any games, nor is there any way to directly access Apple's iTunes Music Store.
Overall the iPhone turns to be the expected device, but Apple should ensure it remains as open as possible to third-party developers as this will make it popular and extend its potential market share.
