You did which was helpful for people that aren't aware so thank you. Maybe rcoone has changed but the last time we tried, it took ages to sync and was timer based. Which means a since file save could take a long time to appear online. When someone has pressed save and walked away from the desk and no update is made online, they get grumpy.
The browser option is frustrating for users, I know I tried it on them once.
Insync, may be worth trying again, it's again an additional cost compared to deployment of Linux compared to the alternatives (where the os is already purchased.) This may not be Ubuntu or gnomes fault but it's extra friction to deployment, and ultimately business goes with what is easy. I do hope google steps in, but seriously doubt it.
