It seems a reasonable start, but it's not exactly user-friendly.
I would think that most people want to know either
1) I have a piece of hardware, does it work with linux/how do i get it to work?
(ie what features are supported? what modules do i need? what kernel/distro version do i need)
2) I want to buy a piece of hardware, what (supported) options do i have?
(ie which models work, where do I buy them, how much are they?)
but that page doesn't seem to be very useful for either of those.
In fact, there's a massive opportunity for someone to make a very useful sight to answer those
questions for general hardware
