Tablet sales are red hot, according to this Memphis Business article. It appears there will be no stopping this trend. Many people mistakenly believed that smart phones were the wave of the future, but let's face reality: one cannot get real work done off a smart phone. Send, receive email from a smart phone? Yes. Maybe look at a PDF or JPEG? Yes. Install some apps for low level of productivity? Yes. But the human eyes are not meant to stare at such small spaces for extended periods of time. So, yes PCs and Mac boxes will go away. Laptops will be around for a little longer but eventually most workers of the world will use a hybrid laptop/tablet to get work done. They will be durable, have lots of hardware resources (RAM, drives) and be touch screen based.
