I have an LG and I really do love it. At first I kept hitting all the wrong buttons and I still do occasionally. But I still prefer way more over a phone without touch screen.
I have an LG Venus, and the top half of the screen, is touch. It's alright. My cousin has the LG Dare and it's so hard to text with, I hate it. The iPhone is alright. I may be getting that.
I don't really like touch screens all that much. My cousin has one, and whenever he puts it in his pocket, it either calls someone, (usually me at six thirty in the morning,) or deletes his pictures and texts.
I have a Motorola Krave, with a clear flip, that's a touch screen, and the main screen is a touch screen, too. I really like it. But sometimes when I touch it, it goes to the completely other side of the screen. And sometimes it doesn't pick up the touch at all.
I hate touch screens personally. I always press the wrong buttons and are either too sensitive or not sensitive enough. I just find them too hard to use :/
