As I've said many times in this space, the future of all computing is -like touch tablets. Within a few years, you'll trade in your old-and-busted WIMP PC (WIMP stands for windows, icons, menus and pointing devices), and embrace something similar to a giant iPad, set at a drafting table angle on your desk.

If this sounds unappealing to you because you don't like on-screen keyboards, you should also know that you'll barely do any typing at all with this PC of the future. Most of the input will be via voice, using a virtual assistant like Siri. What little typing you do will be greatly facilitated by tomorrow's intelligent software that will figure out what you're intending to type and offer to type it for you -- think auto-correct on steroids.

The PC in the future, in other words, uses Siri-like assistant technology as a primary and necessary user interface.

Apple understands this. Google's Andy Rubin, apparently, may not.

As I've written before, Apple is really good at to embrace new ways of doing things. For example, they forced millions to embrace virtual keyboards by banning any company from making a physical keyboard for the original iPhone.
