Is there a benchmark that shows power consumption savings from Veertu in a realistic settings?

In any case, until Veertu support USB devices it is not much use for me.

I just use homebrew and skip the virtualization all together. I only use 2-3% of my battery while riding the train and working for 90 minutes.

What does homebrew have to do with virtualization?

Homebrew is not for replicating a deployment environment in your work machine.

I happen to use Go and a Makefile to build my servers, and my deployment process works on osx and linux, so I end up not having to have to replicate an environment for development.

Even so, Go and a makefile won't account for filesystem differences, databases, services like cron, etc in a deployment environment.

I looked in to Docker on osx, but I am waiting for their latest beta Docker for Mac to come out. I think something like this with a lower learning curve would be more ideal for virtualization. It lowers the feedback loop on experimenting.

I run Postgresql on one of my VPS machines, and I dread having to upgrade it all the time.

You understand why a casual reader, when encountering the statement, "I use 3% of my battery in 90 minutes on my laptop" will raise an eyebrow, right? The extrapolation to total battery life is a little mind boggling.
