The rumors about Gmail’s offline availability have been circulating for months, and finally they’re coming true. Google announced yesterday that users will be able to access Gmail offline.
However, many people won’t necessarily be able to take all their inboxes offline with them; much will depend on the size. Instead the company has developed algorithms to determine which of the messages should be downloaded.
Rajen Sheth, senior product manager for Google Apps, said:
"Gmail was a tough hurdle," adding, "We had to make it such that we’re managing a sizable amount of information offline and doing it well in a way that’s seamless to the end-user."
