My experience with replacing MSOffice with OOo is that everything works well until you get to macros / complex documents. The complex document issue also applies in Windows (try taking big word documents with complex layouts for a round trip between different versions of office and language versions and you will have an electronic version of Chinese whispers). However once you get past the average user you start hitting problems with OOo．Even if you do know OOo's scripting language you do not have the power of MSOffice available to you. A simple example is that in OpenCalc you can't create pull down boxes with pick lists. I used to be a MS Office power user and 18 months ago I switched to SO5.2 recently with the aid of crossover office I've started mixing using OOo and MSOffice and I am so much happier having the power of MSOffice back.
