People are going to compose documents, spreadsheets, etc. on a tablet??
Maybe I need more coffee, can someone explain why anyone would want this?
Compose, no. Edit and update, yes.
Done right, it's actually a crazy powerful workflow.
Here's a trivial example... I do agility training with my dogs. I keep a spreadsheet of skills for each that I need to work on and add a check mark whenever I touch on that skill. I built it on my desktop using Google Drive, and keep a synced, offline version on my phone. Which means I can reference it and add that check mark when I'm actually training, or add a new skill to the list when I'm at class.
Now, is a spreadsheet the right tool for this sort of thing? Maybe a dedicated Android app would be better, but Google Drive is available on every device I care to use.
Obviously I'm assuming that this workflow is viable with whatever toolset Microsoft is offering. I have doubts that they could screw up something so simple, but lately I'm been amazed by their ability to do things exactly the least useful way.
