Palms says that "Microsoft is already engaging in actions designed to unfairly extend its personal computing operating system ("PC OS") monopoly into the mobile computing market by eliminating competition and preventing free customer choice.
1. Microsoft has refused Palm access to information and software interfaces necessary to enable Palm to make its products interoperable with certain Microsoft products and technologies, including some elements of Microsoft's .NET software;
2. Microsoft has prevented Palm from working with Microsoft's software development tools (Microsoft Visual Studio);
3. Microsoft has refused to make Microsoft Internet Explorer operate on Palm OS handhelds; and
4. In exchange for addressing some of these issues, Microsoft has attempted to coerce Palm into deploying Microsoft .NET software on Palm handhelds under terms that would put the Palm OS business at a prohibitive disadvantage.
Microsoft has also already exhibited its intent to foreclose companies such as Palm by breaking interoperability with its products. Bill Gates himself directed his staff to alter Microsoft products to ensure that Microsoft's "PDA will connect to Office in a better way than other PDAs even if that means changing how we do flexible schema in Outlook and how we tie some of our audio and video advanced work to only run on our PDAs.""
