If you thought that the free storage that's offered by Microsoft, Google and others were generous, then you've never been to China. Tencent, in an attempt to crawl past local rivals Baidu and Weibo, is offering customers a whopping 10 Terabytes of space on its Weiyun cloud storage service. All users need to do is sign up with the company, offer up their QQ account number, and download the Weiyun mobile app -- which bags 'em an instant 1TB, with the allowance gradually increasing to 10TB the more files they upload. The only downside for us, naturally, is that the promotion does make SkyDrive's 25GB seem a bit stingy by comparison.
