The report also mentions that the larger model does not feature the Steam button, implying that SteamOS will be exclusive to the Legion Go S model in the new series
IMO, this is a logical move and not a "We ❤ Linux" moment. Lenovo probably saw that Windows was performing abysmally on the lower powered device and it would offer a horrible experience to the users. But I would consider this a small win since this is the first time a big player has officially embraced Linux. This device would be perfect for playing indies and retro gaming and I hope shows people how easy Linux gaming has become.
