Here are the three main features of Google Gears (straight from Google):
| LocalServer |
| Database |
Store data locally in a fully-searchable relational database
Make your web applications more responsive by performing resource-intensive operations asynchronously
From my brief inspection of the API, this makes me rethink my whole opinion of Apollo. You can develop one website with hooks into Gears that gracefully degrades if its not installed. With the Flex/AJAX bridge, you could even have a Flex website that communicates with the Database and WorkerPool. Whoa. Pretty sweet.
I'll post some more thoughts, once I get some time to digest the idea.
