I don't see the actual business case for this at all.
Most businesses amortise a laptop/PC over a number of years. Would you rather pay $10/month/user for this cloud service, or spend the additional $360 (laptop/PC lifespan for a business that can amortise the asset over 3 years) in the first place to get more powerful hardware locally, and benefit all apps rather than just the web browser?
I'd like to be proved wrong.
