I have serious doubts about how comprehensive this support will actually be, especially regarding firmware updates and non-Google vendor commitment.<p>There is a wide variety of Chromebook hardware manufacturers, and most of them don't have a good track record of providing firmware upgrades for long. Google can keep ChromeOS updated on these devices, just like Microsoft can keep pushing Windows updates, but are the manufacturers going to provide firmware updates for 10 years? Are Intel or Mediatek going to be providing 10 years of microcode updates for the CPUs used on these devices? It doesn't make sense to me that these companies are suddenly going to invest a lot of money just to support these cheap devices that probably don't make a lot of profit, when they have never given a similar level of support to their flagship products.<p>I think this 10 year support window will not be full device support, just a commitment to providing OS updates that don't break stuff.
