I waited nearly a month after acquiring a touchscreen phone, to make this post, but now I'm ready to say that for me, a QWERTY is a must and a pure touch phone does not cut it.
I use the Samsung Wave, and some people have told me, iPhone has a better touch screen, a larger display makes a difference, SWYPE on Android is superb etc.
But I find the touchscreen to be responsive and easy to use, so that is not the issue. In fact, I find it way more convenient for some activities like quickly accessing widgets from the homescreen, browsing the net etc. The touchscreen in these cases acts like a mouse, taking me to the portion of the screen that I want to focus my attention on.
The touchscreen irks me when I want to type. When it's an SMS or a mail, I find myself making way more mistakes than I make with a keypad. And it gets worse when I am entering passwords. Maybe I get more butter-fingered because I am concentrating, but what is a simple process with a keyboard, becomes an ordeal on a touch phone. And any typing is rendered more difficult when in a moving vehicle.
The larger sized keyboard, on a landscape orientation solves the problem but only partially. In fact by default, I only use this keyboard as the portrait QWERTY is way too small.
I also miss the tactile feedback of keys. No amount of virtual feedback, either a clicking sound or a vibration, can really compensate for that.
I had blogged earlier about QWERTY phones. Looks like they will be back on my shopping list.
