Essentially they have defined "acceptable" performance across the board and given that a name. If I was looking for cheap hardware it ticks the boxes just about. "AI" is just a transparent marketing attempt at throwing a hot buzzword that most people don't understand into the mix.
Not awful but it really could do with a more ambitious tier, a lot of manufacturers will meet the requirements as set out (all laptops shown have 1080p displays, which is disappointing as many chromebooks had better before, 3:2 and 4k displays). We had 16GB chromebook options nearly a decade ago (mar 2015).
In fact I think would have been preferable if they made this the chromebook minimum requirements and called those with less "chromebook lite" ("Go" already served as this I think?); because celeron/4GB/64GB/<1080p display/webcam is really pushing things for a new device in late 2023 onwards, even as a facebook machine.
PS anyone responsible for the chromebook site out there, most of the device information pages are 404'ing; https://www.google.com/chromebook/discover/pdp-asus-chromebo...
