Not true, Google Maps has added offline storage over the years that is quite helpful, and the feature has gotten better.

Google Docs for Chrome can be used offline as well.

I'm happy google earth is stuck in time and offline. Such a powerful piece of software, like an arcGIS-lite. I get a file tree with folders and subfolders and subsubfolders and points of interests with metadata and notes and layers of everything and anything and I can load other people's content too?? In case you can't tell, it's my favorite google product by far, and they can't ever take it away from me because I have it on my local drive.
