Microsoft Corp, whose only hardware is the Microsoft Mouse, made for the company in the Far East, is planning a more substantial hardware product bearing its name. The Redmond, Washington company has definite plans to enter the gestating Personal Digital Assistant market, also to be made in the Far East, MacWeek reports. The paper suggests that the operating system will not be MS-DOS or its graphical derivatives, but something completely different that the company has developed. And PC Week reports that Microsoft has come up with a method to add pen computing capability to notebook computers for about $300. The US weekly claims that the key to the planned feature is Object Linking & Embedding 2.0, which produces objects that overlay a transparent annotation layer with the ink stored as a scalable data type, so there will be no need for special pen-enabled applications.
