NEW YORK ( TheStreet) -- That laptop died on you one time too many. It became too slow, with too many viruses. The battery deteriorated to the point where it lasted only two hours. It took four minutes to boot up from cold. You always had to sit down in order to use it.In other words, you had enough. It was time for a change. You are now a serious professional who is serious in making the iPad your next laptop -- your main productivity tool, where you type documents.
