It's really amazing to see how far HP has fallen. They used to make brilliant printers that were top-quality, easy to service, and overall met the whole "Just Works" thing.
Then some time in the late 90s/early 2000s they let the bean counters at it, and they've become the poster child of terrible product design optimised to extract the maximum revenue at all costs from customers.
I honestly don't care how revolutionary or awesome a product is - if it's from HP I'm staying away, and would recommend everyone else to do so. The company deserves to die.
