After his presentation John was joined by colleague Anthony Hicks (@anthonyxcom), Jon Nairn (@jonstep, working for @neverodd), Alex Reid (@alexjreid) and Peter Bull (@RoguePlanetoid) for a panel Q&A session.

General points of note from the session and pub discussions:

• Perhaps surprising to some, the iPhone market accounts for a small proportion of mobile devices, and Android mobiles are apparently selling at twice the rate of iPhone.
• iPhone users are generally more comfortable with app purchasing, and represent a more general consumer demographic.
• Submissions and updates are developer-driven for Android, so app deployment can be rapid- especially when compared to Apple’s approval process.
• Development for the less popular platforms may attract incubation or start-up funding.
• Some high-qualify third-party technology exists for integration, e.g. Bump, OpenFeint.
• Commercially, producing good middleware may be a better gamble than a good app.
• Windows Phone 7 Series sounds promising.

Thank you to everybody who attended and James for allowing me to plagiarise his write-up ;)
