In a recent Information Week article, Mitch Wagner reflects on his experience using an iPhone as his primary computer and Internet device for almost three weeks. Wagner writes: “I learned far more about the pluses and minuses of the iPhone during those 21 days than I did during the rest of the 14 weeks that I’ve owned the device. I still like the iPhone a lot, and remain amazed and in awe at some of the things it can do.”

Wagner enthusiastically praises the iPhone’s web browser, suggesting that Apple has clearly worked hard to make sure its browser works well with the overwhelming majority of Web sites without modification of those sites. He also commends the device’s mail client, stating: “I used email to keep in touch with friends at home, and to make plans to meet up with friends and family while traveling, just as if I was still at my home office. That was a terrific experience. “ Wagner was also impressed with the iPhone’s text input device, using it to update his personal blog with about 2,600 words of trip reports.

Despite his general admiration for the device, Wagner does delineate a wish list of iPhone upgrades he is eager to see. He states that he missed having checklist and clipboard applications, as well as a way to create text documents and have them automatically synch to primary computers.

With the recent announcement of Apple’s intent to open the iPhone and iPod touch for 3rd-party development, Wagner’s upgrade wish list is sure to be met sooner rather than later.
