The only point in favour is that it runs on crippled operating systems like ChromeOS.
Google wants us all running Compiler-As-A-Service, Editor-As-A-Service and Debugger-As-A-Service webapps that have Google Analytics and Google Adsense running on them. So they created a crippled OS that can't run Free and Open native apps leaving the users with no choice but to use closed proprietary software services running on some other machine that they don't control
Software as a service is the least free kind of software. We should be fighting hard against it. This is an even more serious fight than the fight against local proprietary software (at least in that fight we still had control of our own data and weren't forced to upgrade to new versions).

The concept of using web-based programs like Google's Gmail is "worse than stupidity", according to a leading advocate of free software.
Richard Stallman, founder of the Free Software Foundation and creator of the computer operating system GNU, said that cloud computing was simply a trap aimed at forcing more people to buy into locked, proprietary systems that would cost them more and more over time.
The 55-year-old New Yorker said that computer users should be keen to keep their information in their own hands, rather than hand it over to a third party.
We need to stop building these traps. If you find yourself using cloud services, think again and consider if there is native software that you could use instead that will run on machines that you control giving you full control over the data and the code.
