I honestly liked the idea when the original PadPhone was first announced, but at the time both smartphones and tablets were a good deal more expensive. Also, at the time of the original's introduction, tethering via smartphone was a no-no on most carriers without an expensive tethering plan... now it's nearly universally accepted on most postpaid carriers.

Now you can have a top-notch tablet and a separate top-notch smartphone for less than the same or less than a PadPhone. I would much rather have two non-dependent devices, especially when traveling, so if one fails the other can still operate. One can be replaced or upgraded without affecting the other. One can be used by one person and the other by another. One can be used while the battery of the other is dead. Etc, etc, so on and so forth.
