Mee too I use it, I sync it with Toodledo.
I think Got To Do is really a good product even if sometimes is not so quick in collecting the new actions, on my Htc.
There is also Due today. I tried it recently but I think, it need some more adjustment by the programmers
I don't now where you live but not in all country you can find it in Android market. So I bought it on Slide Me, even if It cost more. Recently 3,5$
