Apple & MS: Sculley fights with Bill Gates over the introduction of Windows 1.0, which has many similarities to the Mac interface. Gates agreed to sign a statement to the effect that Microsoft would not use Mac technology in Windows 1.0--it said nothing of future versions of Windows, and Gates' lawyers made sure it was airtight. Apple had effectively lost exclusive rights to its interface design. This would prove to be an important document in future lawsuits between Apple and Microsoft, involving the Windows interface.
