Google+ growing fast

-It's Tuesday, July 12, 2011. I'm Wilson Tang on CNET.com and it's time to get Loaded. Google+ may turn out to be the fastest adopted social network in history. A statistical analysis by Paul Allen says the new social network had 7.3 million users on Sunday and will likely hit 10 million users today. The report predicts that if invitations keep flowing, that Google+ will likely reach 20 million users by the end of the weekend. While 20 million users sound like a lot, Facebook really announced that it had 750 million users of which half log in daily. The e-book reader wars continue to heat up but it wasn't until now that any e-reader was natively compatible with Google's e-book store. Now iRiver hopes to be the first with its Story HD device. The Story HD is just 7.3 ounces but packs a high-resolution XGA black and white e-ink display. The Story HD will be available for just $140 with built-in support for Wi-Fi and support for EPUB and PDF formats. Rumors have been heating up that Apple intends to release refreshed versions of its popular MacBook Air laptops. Well, now you can add Mac Pros to the list as well. Part numbers have shown up in retailer databases which point to four new MacBook Air models and four new Mac Pro models. While we don't have any technical details, we do anticipate the new computers will run Intel's Sandy Bridge processors and contain support for Thunderbolt technology. Apple's expected to unveil the new devices when the company launches Mac OS X Lion in the next few days or weeks. Spotify, the popular European music subscription service, has been rumored to land in the US for months now and industry sources have leaked to CNET that the service will be released in the US in limited fashion this week. The launch will be invite-only at first and the company's reportedly working to secure deals with the major music labels. Anonymous is back in the news again and this time, they've taken the battle to the US military. In an operation named Military Meltdown Monday, the hacker collective leaked 90,000 log-ins of military personnel including CENTCOM, SOCOM, the Marine Corps, various Air Force facilities, Homeland Security, the State Department and private contractors. In addition to the log-ins, the hacker group claims to have additional access to sensitive information. Those are your headlines for today, I'm Wilson Tang for CNET.com and you've just been Loaded.
