Touch screen phones are all the rage these days. Everywhere you look, there's some new phone out that offers a 3.5" touch display (usually with no keyboard).
Having owned an iPhone 3G, I am of the firm belief that full touch phones are just a gimmick - their original "wow" factor tends to ware off, and the user is usually left with a user experience that's anything but amazing.
For instance, one major gripe that I have about these types of phones is the inability to "feel" the keyboard, thus allowing you to type without looking at the screen (something I tend to do a little too often). Besides, being able to "feel" a keyboard ensures that you feel "secure" in what you've pressed - you can be sure that that key is what the corresponding writing on-screen will be.
Furthermore, touch screen phones pose the problem of being very delicate devices. A cracked touch screen can run the repair bill up to quite an extraordinary figure - and manufacturers usually don't include the screen as part of the warranty.
While I am an opponent of the advent of touch screen phones, I'm not ruling them out. Touch is the future, we all know that. But what I think is cool is the "hybrid" phones, like most HTC mobiles and Nokia's new N97. These phones offer a ful touch screen for easy, quick access to things like reading new texts, or pulling up contact information. But they also include a full slide-out QWERTY keyboard so that you can compose text in an easier manner.
