Officially supported hardware list

There are several hardware compatibility lists available on the web, but such lists often do not give users clear indications, and have several grey areas. Grey areas are in practice a green flag to "give it a go anyway" even when the user experience cannot be guaranteed to be satisfactory. As a result such lists, while extremely useful, might negatively affect the reputation of Linux distributions and Ubuntu in particular. The aim is to correct this situation by creating a list that draws a clear line between supported and unsupported hardware, eliminating grey areas and disincentivizing users from experimenting with hardware that has a less than satisfactory level of support. It is essential for the hardware list to have an official feeling to it, possibly with a proper certification program. This will help preserve Ubuntu's reputation and incentivize hardware manufacturers.
