Quote from syswizard:
Well, I checked-in with them....and they are simply overwhelmed by the whole project, despite having an agreement with Microsoft.
Look, Guys....Office is complex. Excel alone is UNBELIEVABLY complex...it possibly is the most complex piece of software ever developed when you consider it's programmability and object model. If you look at history, you'll find a guy named Jonathan Sachs, a gifted programmer with a photographic memory, who on his 5th attempt, created Lotus 1-2-3....the precursor to Excel.
I would say OpenOffice is 2-3 YEARS away from cloning Excel satisfactorily. My estimate is that Excel 2003 edition is a compilation of 100+ man-years of effort.
If someone on this group starts now, and is as talented as Sachs, you'll be dead before you finish the job.
It doesn't have to clone Excel or Word exactly and that is not it's aim, though it does aim to be able to read and write MS office documents.
For most purposes OO will do just fine. The major exception is complex applications in Excel using VB. If you are doing that you need to use MS Office.
