We’re moving into that time of year where product announcements are replaced by promotional campaigns and sales figures. Apple revealed it had sold three million assorted iPad tablets in just three days, while Samsung said its Galaxy SIII smartphone had sold more than 30 million units since its launch in May.

We're talking about Apple's iPad mini, the new Google Nexus devices and Microsoft's two updated operating systems in our podcast this week.

There's also the launch of 4G from EE, an assortment of quarterly results and some analysis of smartphone sales.

This week we're talking about the UK's first 4G mobile phone tariffs, Ofcom's consultation about contract pricing and O2's response to its recent network outage.

We're also looking at quarterly results from Google and Nokia, Apple's iPad design, Microsoft's tablet pricing and texting cows.

If you want to understand mobile gaming, from the commercial side of game development to the current trends in game design, Sandy Duncan is a great person to talk to.

He spent over 16 years at Microsoft, initially working with PC manufacturers and latterly setting up the company’s Xbox game console business in Europe. He’s an enthusiastic gamer. And, for the last six years, he’s been CEO of YoYo Games.

I started my conversation with Sandy by asking him why there was so much interest in mobile gaming when PCs and dedicated consoles were always going to be more powerful than smartphones.

The last time I used a Microsoft based mobile phone was 2008 in the form of the HTC Hermes. Since then Apple and Android have dominated my mobile life. It was therefore with more than a little trepidation that I switched over to Windows Phone 7.5 in the form of the Lumia 800 in July this year. Since then I’m continually being asked what I think of the phone and the operating system. Here are my experiences and thoughts.
