EMC held its huge annual show for customers, analysts and reporters this week. Here are 10 things we learned.

1. More than 9,000 people from 85 countries attended EMC World, held at the Mandalay Bay in Las Vegas. That includes more than 80 journalists from 36 countries, including Germany, Canada, Egypt, Finland and France.

2. One Chinese journalist had to bow out of the event to cover the aftermath of an earthquake that killed more than 34,000 people in his home country. EMC raised US$175,000 from its 38,000 employees for humanitarian aid that will be sent to the devastated regions of China, according to EMC spokesman Michael Gallant.

3. The eagerly anticipated cloud storage software code-named Maui will ship this US summer, EMC president and CEO Joe Tucci told reporters. EMC has been secretive about its future cloud storage offering, which will combine the Maui software with EMC's Hulk hardware, a bulk, high-density storage device. Hulk has been shipping in beta for several months, but EMC is waiting until both are ready before making a big public splash.

"You'll see it launched with a formal name and fanfare shortly," Tucci said.

4. EMC has averaged US$1.8 billion in annual spending on acquisitions over the past four years, and Tucci said EMC will continue acquiring companies to bolster all five of its core businesses: data storage, content management and archiving, RSA security, virtualization, and cloud computing.

5. Tucci mentioned that EMC acquired three companies in Israel in 2006: ProActivity, Kashya, and nLayers. He hinted at more activity in that country.

"We're very committed to Israel and you'll see us even more in Israel," Tucci said. EMC will continue to increase its focus on the Middle East and other growing technology regions, including Latin America, Tucci added. "We're going to increase funding there. We're not even close to tapping the potential."

6. In his keynote address, Tucci talked about an IDC calculator that lets people figure out how much digital information they create. Tucci revealed his own "digital footprint," which amounts to 3.8 gigabytes a day based on sending and receiving 250 e-mails a week, watching recorded television, and taking digital photographs. But your digital footprint grows larger not just through you're own actions but also when you're caught on surveillance cameras.

"I was walking through the streets of London last week," Tucci said. "There was a sign that said 'you will be captured digitally on camera 20 times today.' There was a punchline saying 'how are you dressed?' If you walk through airports, if you walk the streets of London or a lot of major cities, you're being captured constantly."
