Same here. The doc provided contains very few working examples. Support on forums is nearly non-existent. They have good tutorials videos but once you start adding functionality it hits the fan. I originally wanted to save dev time but unless you're making a static app, or a RSS feed you better go with java or objective-c.
Oh dear... I'm looking forward to build a prototype soon then.
Indeed when searching through their forums for a spreadsheet style grid component I found plenty of unanswered topics.
