No post-PC era
Pro post-PC era
Best Argument: Pro post-PC era
Post-PC era is bunk
Zack Whittaker: This just in: The PC is not dead. I'll concede that the mouse is making its way to the scrap heap---along with the USB flash drive and DVDs. However, the QWERTY-keyboard reigns as the all-mighty technology. No tablet, iPad or smartphone can take the QWERTY away from us. Touch-keyboards are terrible for writing essays or lengthy word documents, and smartphones only work if you have dainty hands. The traditional PC is not dead---it's just evolving. We see them in offices, homes, Internet cafes, and for good reason. They remain the 'base' device we use to make things happen -- whether it's CAD drawing for engineers or PhotoShop for designers.
All this "post-PC era" talk is bunk. The iPad isn't a PC, and never will be. While Jason thinks in MIPS, beeps and chips, he's delusional about the post-PC era. If we adopted his view today, we'd be blinded by shiny objects and suffer from plunging productivity. Even worse, we'd be saddled with "post-PC junk."
Post-PC era is here already
Jason Perlow: We are living in the beginning of what Steve Jobs called the "post-PC" age. But what does "post-PC" actually mean? Tablets such as the iPad, and other light computing devices, are going to replace the PC. I'd argue that the post-PC era encompasses a broad set of technologies that will eventually kill the PC as we know it today.
What do I mean? The x86 platform---30 years old this month---is toast. Speed, storage, graphics and I/O have all improved, but we're on an architecture not much different than the original 5150 PC. The PC architecture---hatched at IBM and turned into a standard by Wintel---is almost certainly in its final decade in the consumer space. We have entered a post-PC era and that means the x86 is going extinct. Personal computing won't disappear, but the PC as we know it will. The platforms delivering the post-PC era---ARM, tablets, smartphones, cloud computing---will bear no resemblance whatsoever to the PC. I guarantee it.
