Hybrid Sweet Spot
David writing on Signal v. Noise about building mobile version of Basecamp:
We implemented the main progress screen in the iPhone app in first a fully native version, then again in an HTML-backed version.
After a fiddling a bit, the conclusion was clear: There was no discernible difference! Well, except for the fact that it was far quicker to develop the HTML version than the native version.
Count me in for this approach.
