ohhh. Well for those that don't use a phone, this is not an issue for them because the mobile display will only be for smartphones and iphones. Windows and Blackberrys (some) will be excluded. The app however, can be downloaded via the app store.
As for those that like using the desktop mode on their phones, they can exit out of the mobile mode and that should keep them in the desktop mode for 90 days maximum provided that they don't clear their browser cache and cookies.
You can ask us any questions regarding the app and the site here and we'll try to answer them as best as we can.
