I would advocate Chromebooks and Chromeboxes only because once I remove the bootloader protection, flash the coreboot firmware and install whichever OS I want, from my point of view they're wonderful little machines. But from normal users perspective, once they discover that the hardware is locked to prevent the install of anything but ChromeOS, they are garbage, and probably it is what they become once the user has enough of the Google ecosystem then ditch them well before their physical obsolescence. Locking down hardware to prevent installation of other operating systems should become illegal.
