It seems that without providing data synchronization out of the box, Google Gears leaves the most difficult and cumbersome aspect of building a disconnected Web app up to application developers. This may be OK for Google developers using Google Gears since the average Google coder is a Ph.D but the platform isn’t terribly useful to Web application developers who want to use it for anything besides a super-sized HTTP cookie.
gears does not solve all problems in the sync space!!! film at 11.
