 Please review my DropZap web demo.  It's written using GWT.
richardw: My guess is: put the 9/10 from the iPhone App review near the top. Simplify the page and reduce the importance of most of the text - lots of colours demanding attention. Get it to 1 message and the game.However I suspect the real answers will emerge from testing. Do a test on trial screen count and see which amount of screens increases your conversion. Test changing colours, text, positioning etc. Over time you'll know more than we could about what will work on that page.
