The source is anybody's guess at this point. Reactor accident in Russia, low-yield nuke test?
A cheap Android phone bought on EBay. Have exactly NO data on it, but lock it with a long password. If they try to bully you into giving up the password, let the fucking pigs confiscate it.
Why? For $10 or $20, you can waste a lot of their time -- let them crack the encryption to yield exactly zilch. The best way to fight Trumpian authoritarianism is to gum up the system and overload the pigs who are "just doing their jobs" with unnecessary, wasteful work.
To be clear, it does also support Sharepoint, which some larger businesses have, so using the cloud is not mandatory. But not supporting local file storage might be OK on an iOS device where the file system is hidden from the user, but not on Android which has decent support for local and SD card storage.
Smacks of Microsoft wanting to own all of their users' data. I'll stick with Kingsoft Office or OpenOffice for Android, thanks very much. I really don't want to upload all of my private data to the Great Fluffy Mothership in Redmond, nor do I intend to pay for a license to run a Sharepoint server.
Shows how blind Microsoft is. Unlike iOS devices, Android comes with decent support for local file storage out of the box. Apparently, Mobile Office only currently supports opening files on SkyDrive/OneDrive. No support for local storage, so that email attachment that you downloaded with the native Android email client won't be readable unless you upload it to the mothership in Redmond first. Same goes with files created with other Android apps.
Nor does it have support for Dropbox, Box.net, or other cloud services that people use for business file sharing.
