I have the iPod touch as you know and from an earlier post regarding its battery, you can probably tell that I use my touch as one of my main mobile device. It's an valued part of my mobile workflow. I almost leave home without it. At times, I cannot help but think that Apple is using the iPod touch as a way to introduce people to the iPhone, especially for those who cannot afford a two-year commitment that is required to own an iPhone. And for kids in school, the touch is a great way to get them ready for the iPhone someday.
Instead of seeing the iPod touch as a device to help Apple up sell users to the iPhone, I think Cupertino needs to reevaluate this and perhaps give the iPod touch just as much innovative and marketing attention as the iPhone.
With the introduction of the fourth generation iPod touch with Facetime camera running iOS 4, this touch has has true become a mobile device with a lot of productive power. Yes, it is missing 3G wireless access but it more than makes up for not having the need for the user to sign up for a two-year contract. At the same time, it has the clear Retina display the iPhone 4 has and has similar specs on the inside as well. In a Wi-Fi environment, the touch loses nothing to the iPhone.
In fact, this is what I think Apple should do. As with its back-to-school deal that gives each student a free iPod touch with the purchase of a Mac, Apple should expand this to everyone. Apple should offer this to enterprise customers as well as individuals.
