The only sensible reason for keeping humans in the Matrix

There have been many discussions on if humans are imprisoned in a simulated reality such as presented in the movie The Matrix. In the Matrix, the reason for imprisoning humans is to extract energy. A reason not very plausible, since it would be much less trouble to keep, say, pigs. They could perform the same function and cause much less razzling. In the book Under the skin from 2000 Michael Faber instead keeps the humans for meet production. Now, also this is something pigs would do better.

So, what reasons are the for aliens or machines or other humans to imprison humans. Well, I can only see one: for the computing power of our brains. It is reasonable to assume that there is something unique with the human brain. Unique enough that it could be worth the trouble of creating a simulation like the Matrix. What do you think? Any other reason?

Why are we still using Bluetooth?!

I have never used a pair of Bluetooth devices that works flawlessly. The latest addition to the set, is my new Windows 8/ASUS laptop which simply refuses to find my Sony Bluetooth headset.

Whys is this, and why is there no improvement. I have been frustrated with this now for 10 years, and the same issues still persist. What is the wireless community planning to do about this?
