This week's Question: Last year, Apple CEO Steve Jobs said users are moving toward a "post-PC world," and computer sales have indeed slowed. Perhaps demonstrating Jobs' "post-PC" concept, the information technology giant HP recently announced that it would stop producing tablet computers and mobile phones, and that it is considering the sale of its PC division. Smartphone and tablet sales have increased, but many users still consider their Windows machines and Macs to be their central computing devices, and that new mobile technologies are complementing desktops and laptops rather than replacing them.   What do you think? Will the PC be replaced by tablets and mobile devices?   RESULTS
