Well, Google took care of that issue today.

At its annual on Thursday, Google announced that it is adding the ability to work offline to , the company's cloud-based office apps.

That means people working on shared documents will be able to do their work offline and then when they are back online, their document will automatically sync up with the cloud.

Such offline capability could be handy for people who might need to work while travelling by plane without wireless Internet access, as well as for people who need to keep working when the network goes down.

Dan Olds, an analyst with The Gabriel Consulting Group, said this is a good move for Google Docs but he's not sure why it took Google so long to do it.
