Unfortunately for them, they face stiff competition from streaming-enabled smartphones and tablets, many of which are perfectly good games devices, and it's just a matter of time before Apple TV gets Angry Birds.

8. Firms that don't make hardware making hardware
In 2012 we saw the Nexus 7, 4 and 10, Amazon's Kindle Fires, Barnes & Noble's Nooks and Microsoft's Surface, and the trend will continue in 2013: Amazon is reportedly working on a smartphone and Facebook might be; Microsoft plans to make more Surfaces next year and possibly a phone too; and more Kindle Fires and Nooks are clearly coming too.
2013 will be all about the ecosystems, not just the hardware: firms will increasingly want to sell you everything from soup to nuts, and if that means getting into the hardware business then so be it.
9. Gadgets made in the USA
This could be a trend: firms such as GM and GE are 'insourcing', going back to hiring people in the US instead of subcontracting to overseas suppliers.
For many firms, outsourcing's benefits have disappeared amid record oil price rises (which massively increases shipping costs), rising Asian wages, increased Western productivity and lower energy bills due to the current natural gas boom.
According to The Atlantic, when GE insourced the manufacturing of expensive water heaters, it found that it could make them faster, to a higher standard and for less money than by outsourcing the work.
10. Everything connected to everything else
It's all coming together: as basic networking tech gets smaller and cheaper it becomes more widespread, and before you know it you've got everything from fitness trackers to thermostats, door locks and lightbulbs, connecting to a router or talking to your smartphone.
From cars to coffee machines, if it's possible to control it with an app, someone's going to find a way to do it.
