Google Gears - GApollo?

Just found this one - Google Gears.

Seems that idea of making web applications capable to work offline is quite popular these days. Pioneered by Adobe Apollo and now we have Google Gears.
Looking at the list of supported browsers

Apple Mac OS X (10.2 or higher)
Firefox 1.5 or higher
Linux
Firefox 1.5 or higher
Microsoft Windows (XP or higher)
Firefox 1.5 or higher
Internet Explorer 6 or higher

am not impressed that much. Second, is the "clever" idea to put SQL statements in javascript code - it's very easy to hack the application if you know the database structure. And finally you will get the famous Google attitude - it's free so we won't bother making it look nice and easy to understand - the samples are ugly, the documentation is far from perfect.
