ALT+TAB: Huffington Post alerts us to a new study which found that using a laptop to take notes in class reduced college students' grades by an average of 11%, compared to those who used pen and paper. But that's not all: researchers also found that students who use pen and paper could be affected when surrounded by those using laptops; they suffered grades that averaged 17% lower than the those without the distraction. One researcher found that "peers who were seated around multitaskers had no idea they were being distracted." Beware the dangers of second-hand computing!
