[...]With a logo a PC vendor such as Dell can stick the logo on their PCs
if and only if every component in the machine is certified.
(Including motherboard, on-board graphics, on-boad-sound, on-board
raid etc. etc.)
This means you or I don't have to try to find out the exact machine
specification from Dell and then individually check each part against
the hardware database.
I completely agree with all your arguments. My point is that your
solution is a long term one. It depends on demand being there, on
hardware vendors to be educated/lobbied/pressured, on both part
vendors and part assemblers to use the logos (as a good side effect
creating the logo might enforce the existance of Linux/Free OS
specialized hardware companies).
This is a good but long term shot. It will take years before such a
framework becomes effective for the user.
The primary motivation for this is that it leverages the individual power of each purchaser (of a system or individual piece of hardware) be they a consumer, SME, system builder, tier 1 or 2 PC manufacturer, government dept., or Linux distro company, into a single point of pressure that can be applied to OEMs to ensure that they provide open source drivers.
