Having just arrived back from this year's mobile mega bash MWC, I thought I'd pen a few thoughts. Despite the cold and rain it felt like the first time MWC was finally comfortable in its 'not so new' home of Barcelona. The mood was one of optimism after a forgettable 2009.

I think that Rick Wray at the Observer called the main vibe on Sunday before a ball was even kicked. His piece on the power shift from Europe to the US in mobile was spot on. The iPhone has changed everything, and the mobile OS wars will be fought out between the US giants. A few years back Microsoft wouldn't have dreamed of making such a huge splash at the show, apparently they had 350 people there this year!

With the iPad on its way there were more than a few companies relived they could get their offerings out in the tablet market before that bomb is fully detonated. And so the battlegrounds are drawn for next year.

The easy way to Barcelona? A 48 hour unplanned stopover in Munich. Yay.

As always the best stuff is to be found when pounding the floors. The best company I bumped into was Mflex. I'm no expert but they apparently do high density component assembly. Their explanation was that without their tech the iPhone it would have been 4mm thicker - that would have made it a veritable brick. I certainly wouldn't have bought one.

From the big boys DoCoMo had a huge traffic surge when Stephen Fry tweeted about its new eye-movement controlled headphones  - "impossibly brilliant" he bleated. They were.

Lastly, It's always great to see the UK PR industry out in force with all the fragile bravado of a hard copy telco publication. Maybe next year the whole UK PR contingent should charter its own plane. It would be more fun and at least Easyjet wouldn't keep us waiting all weekend.
