Windows expert Paul Thurrott got his hands on a copy of Office 15, currently available only as a secret Technical Preview which Microsoft hasn’t said much about. He has some details and a ton of screenshots on the new version of the suite — which apparently tries to split the difference between Windows 8’s all new interface and old-style Windows. It’s a logical approach, but a tricky one to do well, and it’ll be fascinating to see if Microsoft pulls it off.
