With the 30th anniversary of the IBM 5150 (running MS-DOS) coming this week, IBM CTO Mark Dean argues that the post-PC world is very much upon us, perhaps not surprising given that IBM sold its PC business in 2005. Microsoft, of course, weighed in as well, saying the PC era is nowhere near over. But perhaps in the future we will consider a personal computer anything a person does computing on — whether that be laptop, tablet, smartphone, or something that hasn't even been invented yet."
