I'm totally with you. After I've aquired a smartphone (HTC Desire), I've come to the conclusion that the only thing that touchscreens are good for is scrolling. I hate writing on it, I hate pushing buttons and links, I hate that the virtual objects that I interact with gets occluded by my fingers, I hate that I have to hold my phone in awkward ways so I don't accidentally "push" virtual "buttons". Many of these irritations stem from the fact that the interface has no tactile feedback, and does not respond to different levels of pressure (like ordinary buttons).
Touchscreens are a regression in user interfaces, and I hope that the future will bring a comeback of more tactile input devices, like keyboards.
