Google's much-anticipated plan to merge Android and ChromeOS into a single operating system called Aluminium is shaping up to be a drawn-out, complicated transition that could leave existing Chromebook users behind, according to previously unreported court documents in the Google search antitrust case. The new OS won't be compatible with all existing Chromebook hardware, and Google will be forced to maintain ChromeOS through at least 2033 to honor its 10-year support commitment to current users -- meaning two parallel operating systems running for years. The timeline itself is messier than Google has let on publicly, the filings suggest. Sameer Samat, Google's head of Android, called the merger "something we're super excited about for next year" last September, but court filings describe the "fastest path" to market as offering Aluminium to "commercial trusted testers" in late 2026 before a full release in 2028. Enterprise and education customers -- the segments where Chromebooks currently dominate -- are slated for 2028 as well. Columbia computer science professor Jason Nieh, who interviewed Google engineers as a witness in the case, testified that Aluminium requires a heavier software stack and more powerful hardware to run.
