>My Roku is the size it is not because it needs to be that big to hold components, but so that it looks substantial to consumers and doesn't get lost in a ball of cables.

Are you sure its not because multiple-generations-removed miniaturization technology is cheaper, and the latest Roku devices are under $100? Or that perhaps it's a different economic driver, rather than so the consumer sees its physical size?

Regarding the second app, I think the issue is again non-technical -- content is not available across devices because it's a differentiator. It may seem an artificial barrier -- your Roku can decode any video stream -- but the structure of a system that created the content suggests otherwise.

Sounds like things are ready for interoperation except for the human/economic/structural element.

I think the idea is that a security professional should use, on a regular basis, multiple email clients.

It's a funny trick of the english language that when we say someone uses an email client, it comes across as an exclusive use. We need an explicit patch.

Pay with a burner credit card, throwaway account? Access via VPN / LiveCD if concerned?

23andme knows my DNA. They know my email, and possibly where I bought the kit.

They don't know who I am, I hope.

And, regardless, I suspect the de-anonymization will be either so haphazard or so thorough in the future that it's not a primary concern.

Of course a bicycle that is what... 1.2x human weight... is more efficient than a car that is probably ~10x human weight, when you measure it by vehicle rather than kcal per mass.
