I'll admit I'm a MS fan, but if they sued me for 54 mil i'd be riping their shit out as fast as I can. I'm sure for that price tag I could find some one to custom write all the software I needed. Open source or closed source. even I did when the law suit I would fore bid any one from using MS stuff on pain of being publicly flogged and hung from their gentials.
I understand why some people still use oracle but I would never use SAP. It seams every time I hear about a SAP project it ends in tears.
