I've installed HAL in my Arch box just to see if it'll work, and nope, it still doesn't.
Not in Firefox with the last supported Flash for Linux that uses NPAPI (18.104.22.1680), nor on Chromium, with Pepper Flash (11.6.602.171). hald is running and everything.
Why don't these guys learn from Steam? Make an effort, and they get some of the most loyal, most vocal platform zealots money can never buy; shun them, they get the most rabid haters.
I seriously hope Amazon reconsiders this move. I was this close to actually paying for an Amazon Prime subscription, but since I won't be able to stream on my PC (which solely runs Linux) nor on my phone (Android 4.1), they just lost a potential loyal customer to piracy (I downloaded Zombieland and Alpha House through TPB).
The cost of feathers has risen, even down is up!
