Apple may be developing a stylus pen to go with the iPad in an effort to appeal to students, The New York Times reported. According to the blog Patently Apple, the company filed a patent in 2008 for a special stylus that works with its touchscreen devices. The Times quoted an anonymous source at Apple who said a stylus could increase the utility of the iPad in education. “It’s one of the barriers for school kids and college students to purchase an iPad where they want the ability to take notes by hand and draw in class,” the Times quoted the source as saying. A number of students and professors have noted as much to Inside Higher Ed. A second version of the iPad is expected to be unveiled this spring.
