There's been a lot of discussion about how the iPhone doesn't pose a threat to the DS (and we agree wholeheartedly). Even so, we have to admit that the iPhone is nice in theory -- that is, having every kind of portable device wrapped up in one small package. Then again, it's also nice to have a device completely dedicated to gaming, as that inspires more confidence when it comes to our favorite hobby.
What do you think, though? Ideally, would you prefer having a single, multipurpose device so that you wouldn't have to carry around a bunch of different portables? Or, would you rather have everything made with one specific use in mind?
