People on older OS's still have the option of continuing to use their current working version of MobileSheets, don't they?  They just won't get updates any more?  I can see how if you have an older tablet that's still working you might want to just keep using it as is.  (And perhaps you can mitigate the security issues if you don't use it for anything else.)  But then sticking with old MobileSheets seems reasonable for that case.

Is it a problem for new installs?  E.g. if I pick up an old tablet and want to install MobileSheets on it, is there a way to request an older version of the app?
