In the market for a new cell phone...i currently have the iPhone 3G (which I hate) what can I get that works similarly and synchs up with a MAC computer (so I don't have to manually enter all contacts and what not)?

Ok…so I have been through about 8 iPhones. I hate that the touch screen always activates something while the phone is touching my face (all the sudden the person I am speaking with either can’t hear me because I have inadvertently pressed the mute button or they are suddenly on speaker phone for the world to hear). I’m over it!!! I like that it easily synchs up to my MAC computer though, and I also like that it has my itunes so I don’t also need an iPod. I realize I may be asking for too much. I don’t have a land line, so this is a very important decision, and I would very much appreciate any help/advice on this urgent matter.
