The holy grail in Mobile is being able to support the major mobile platforms with one codebase. HTML is not (yet) the answer. Codename One has a few examples of high quality Apps built with their toolchain, so it is definitely worth looking at.
Has anyone used this framework in anger? No support for sqlite would stop me from porting my Android app to this. It looks like they have focused on the UI only so far (to good effect!)
