Pretty stoked about the news of this Echo device. I've got a PC running the InfiniTV 4 with 2 extenders (Xbox) in the house. I've been absolutely thrilled with it but the Echo could make it so much better!
If the Echo can:
1. Allow me to do Netflix/Hulu/Youtube
2. Natively support MKVs and many other formats
3. Pop a blu-ray into the host PC's blu-ray drive and stream it to the Echo
I'd buy one for every TV in the house and every TV in all my friends', families', coworkers', and strangers' houses.
I think that 1 and 2 would be simple enough? 3 would be great but I'm not sure if it'd be possible. I just want to play a DVD/Blu-ray from the host's drive on my extender! I refuse to pay for Live Gold to do Netflix currently since I don't game. I've also tried a few Netflix plugins but they don't seem to work anymore; same with youtube plugins. Regardless of what the outcome is of the Echo, it'll hopefully ignite the media center platform and help propel it past it's previous state.
