Who to point the finger at? Microsoft or HP?

Andrew Garcia, blogging for E-Week, gives a luke warm review of Vista SP1. He finally installed Vista onto his everyday use PC, as opposed to the magazine's lab machines that he doesn't have to face up to every day. Andrew finds the Vista won't work his HP Laserjet 1000 printer. "The HP website had a note from December 2006 saying Vista drivers were coming soon, but there has been no further news in the intervening 14 months. It's disappointing, but I can't blame Microsoft for HP dropping the ball."
Well Andrew, I do blame Microsoft for making unnecessary Windows changes that broke a working driver. Every couple of years Microsoft changes Windows and everyone in the industry has to redo all the drivers for their products, just 'cause Microsoft changed the way Windows works, again.
