Carl Weinschenk from ITBusinessEdge calls the iPhone a "Milestone in Business Mobility". But can Apple really lure corporate customers with what is clearly a consumer play? I don't see that happening. iPhone is, by design, an entertainment device...not a business oriented mobile productivity tool like the Treo or Blackberry. It would be nice to see the IT world embrace such a lavish smartphone, but it's going to take much more than style and software elegance to dislodge Blackberry.
