IBM can! Pretty much everyone has stopped using Office and has moved to Symphony. There are still rare cases but for the most part I only get Symphony files in my email now.
Interesting article on InfoWorld.
Lotus Symphony, on the other hand, is a mixed bag. It has three well-designed applications, but the suite as a whole is not as capable as OpenOffice or Zoho because it doesn't provide database, communications, or collaboration capabilities. If you handle those in some other way, Symphony could ably take on the big functions of personal productivity: word processing, spreadsheets, and presentations. Symphony Write is especially capable at creating and organizing complex documents — with a more comprehensive supporting cast, it could be a real competitor in this market.
They seem to put too much weight on database (MS Access), who really uses MS Access on a day to day basis? 🙂
