After trial run with Office 2007 I returned to Office 2003 (for heroic imposed and held 8 weeks) again. The highly acclaimed productivity improvement was equally failed as a rapid familiarization with the new surface. The features required were not exactly where they should have expected, and then time-consuming search was announced. What most disturbs this: There is no button of a "look and feel" allows a so far, familiar user interface style. By the way many, which I passed on these texts could not open I-had saved in the new format ....
So I will not change (still prefer to OpenOffice!) - And recommend any one test run. Buys 2003 long as there is that!
