It's here. It's ready. It's sitting in your Christmas stocking, peering out as you sleep. It's the Popular Science Christmas issue!

As always, we look to the future. We look to the next stage in mobile computing, and put together the best phone concept money can't actually buy just yet - 1920x1080 screen, built in Kinect, carbon fibre design. Don't worry, we'll get around to actually making it eventually.

We also explore the latest and greatest tech, innovating in spaces such as aerospace and computing, and work out where we're likely to head in the near future.

And the future wouldn't be complete without a futurist, and we speak to Australian futurist Mark Pesce, picking his brain on the next future years of social and technological development.

But, being at the tail end of yet another(!) year, we look back at the tech we already have, as we bring you our annual gift guide? Trying to avoid gifting your rellies with sushi USB drives again? Fret no more!

Oh, and steam powered cars. Yeah, they're still around, and still cool.

All of this and more, in PopSci#38. Dig in!
