I assume that the vast majority of Roku owners never come to this board, but then again who knows; only Roku.
Actually, I would imagine that most Roku owners hang out here and have a technical background. If you are one of the early HD1000 owners you know that initially it was a disaster, firmware wise. Who but us technonuts would have had the patients (and understanding) to stay with this products through its evolution. If it hadn't been for the unpaid, third party developers and user community that hang out on this forum, the HD1000 would have remained as useless as the day it originally shipped.
As a small startup, with limited resources, I don't fault Roku for rushing its first product out the door in the hopes of generating sustaining revenue. What I do fault Roku for is not doing right by those that have supported it from the very beginning. As a hardware engineer, you know that it is standard practice to subject new products extreme temperature, humidity, over and under voltage, etc. in a test chamber before moving them into production. If you don't have this capability in-house, there are many testing companies here in the Valley that will do the job for you. Do you think that Roku did this? I sincerely doubt it.
Anyway, by now it must be obvious to Roku that the messed-up as far as the heat load of the box, power supply rating, etc. Charging its loyal customers $75 for a replacement power supply just isn't the way to make amends. Labor and shipping costs being what they are, they may want to stick with this price for units they repair, but they should also make available a cheaper, field installable unit. I kludged up a couple external power supplies to keep my HD1000's running and really wouldn't want to pull them out of service to send them to Roku. I would much rather install the new supply myself.
