The current special says sign up for $1 down, $10/month, no commitment. What does no commitment mean? Can I cancel after 2 months with no penalty?

Yes you can cancel at any time. However I believe they require your cancellation to be submitted in writing. There is also an annual fee that they charge in November on the 1st. The fee is $41.63 with tax.

Yes, cancell anytime. No penalties. Also you come when you want.

I believe so.
