Adoption of the iPhone has surpassed all industry and analyst expectations. The iPhone is ready for business, with 4 million units sold in 2007 and 10 million projected in 2008. Microsoft Exchange Server integration is one of the key features driving the iPhone's readiness in an business environment. Meanwhile the iPhone lacks a few key features: search, copy/paste, audio/visual recording, printing, Java or Flash in the browser, 3G, data tethering, limited camera quality, limited 128MB program memory, etc. But with a quickly expanding ecosystem, a new SDK, and a wave of new applications on the horizon, the iPhone is exceeding expectations wherever it's adopted.
