Why would I want to use 2 hands to use my phone?
That isn't very efficient.
Can't drive and text.
Can't carry stuff while using the phone.
Can't hold onto railing on public transportation and use phone.

Multi-touch is nice to have when I used two hands.
What's also nice to have is the ability to use my phone with one hand.
BOTH are important to ME as well as others.
