Although organisers reported a 20 percent drop in attendees at CeBIT 2009, those who did visit the trade show in Hannover last week had plenty of gadgets, and even a movie legend, to keep them occupied.

As well as writing up the big announcements as they happened on our news pages and via our Twitter page, PC Advisor covered the CeBIT highlights on PCA TV.

Here's our pick of the top videos from this year's show.

Arnie does CeBIT

Gone are the days when Arnold Schwarzenegger was tasked with saving the world - now he's focusing on simply saving the world economy. The Governor of California said at CeBIT that attendees should "become part of the solution", not part of the problem, when dealing with the current financial crisis. And despite now being a serious politician, he couldn't resist wrapping up proceedings with his most famous film line.
