MSNBC.com technology writer, Joe Hutsko, purchased an iPhone to replace his Treo 680 (a common trend it seems) and decided to put the much hyped gadget to the test, to see whether iPhone is road worthy as a laptop replacement.

Can I type as quickly on it as I can on my MacBook or any real keyboard? No. As fast as on my Treo 680? Yes. Faster, actually. And comfortably enough that I can imagine getting real editing work done once there’s a Word-compatible editor for the iPhone. And not just editing, but real writing too, as demonstrated by this story — the first draft of which was written entirely on the iPhone.

Joe was so impressed with iPhone's proven mobile computing potential he sees it replacing the role currently served by laptops.
