1. Personally, there are few times where I actually wanted or needed to use a touch screen phone one handed. Also, I've seen people who are very adept at using touch screen phones one handed. It just takes practice.
2. I figured that the idea of having a screen is so it would display some information that is useful to the person using it. There are very few applications where you don't want to or need to actually look at some output that is displayed on the screen.
3. No argument here.
4. Hard? If it is hard for you to pick up a touchscreen phone without pushing buttons, I think you have some issues with your manual dexterity. Non-touch screen phones are also prone to accidental button pushes. That is why non-touchscreen phones, allow you to lock the keyboard.
5. The loss of robustness is more than made up by the features of a touchscreen.
6. This is an issue with the UI. You could easily design a crappy UI for a non-touchscreen phone that required you to do the exact same thing. Many
7. Playing action games on my non-multitouch resistive touchscreen phone sucks. It's hard to look at the action on the screen and know where to press on the touch screen to take the appropriate action. Games ideally should be played with some type of controller where I can feel with my fingers. That way if I want to say move up, I do not need to look for the up arrow on the touch screen control pad and then press it. I would often press the wrong spot or miss something as I am not looking at the action in the game.
. For non-action games, touch screens work fine. Some games require you select a particular section of the game screen. With a touch screen, you don't need to use a D-pad to move the pointer across different selections to reach the spot on the screen you want to select. You just point to it and touch it right away. Depending on the type of game, touchscreens may be better.
8. You will run into the same issues with a non-touchscreen phone if you want to interact with it while it is cradled on your dash giving turn-by-turn instructions. I've used a Blackberry non-touchscreen phone as well as my N97 touchscreen phone while using mapping software while driving. Both are just as cumbersome to use. For both, you have to actually look on the screen from time to time and pressing buttons while the car is being jolted due to the bumps on the road. It is just as easy to press the wrong button as it is to press the wrong spot on a touchscreen.
9. The difficulty of inputting text is more due to your familiarity with the input device and your proficiency with entering text on it. I know someone who can enter text much faster on his iPhone touchscreen keyboard than I can on my N97 slide out keyboard. I can also enter text way faster on my N97 than on my Blackberry keyboard because I am more familiar with the N97 than with the Blackberry. If you are having difficulties with the touchscreen keyboard or any keyboard for that matter, it is likely you are simply not as familiar with it compared to something else. You cannot blame touchscreens for your lack of proficiency with the input device.
10. Good luck using your mapping software on your 2.6", non-touchscreen while it is on your dashboard 2-feet away from your eyes. Meanwhile, I can comfortably see the roads on my 3.5" screen from that same distance. If my screen were 4", I can see the maps even more comfortably. I never would have thought that having a smaller screen would be such a big benefit. If you feel that you want something even smaller than the 2.6" screen, perhaps you can use those phones with 7-segment displays. The result can be a form factor whcih can be even dramatically smaller. I think Zoolander has one of those phones.
