Sleep Cycle, a sleep tracking alarm clock for iOS, uses the accelerometer to implement snooze with a smack of the phone (while it is on your bed), while the alarm off is the de facto slide to the right. I think this is about the best phone alarm clock I've used for this feature alone. It is so similar to interacting with a regular alarm clock.

I've never used a real alarm clock, but I do feel like it is easier to wake up with sleep cycle. It is also awesome that you have a limited number of snoozes, after those it doesn't stop ringing.
