Microsoft has donated over $60K to Sage development over the years (these are as 100% pure gifts -- never ever a contract) . When I say "Microsoft" I really mean a particular person (Kristen Lauter) was able to get Microsoft to donate. I try not to make her difficult job of extracting a donation from Microsoft even harder. > >> This new Ubuntu in Windows initiative is really fantastic.
