>Yeah, get back to us when tablets have more than 64GBs of storage, and don't need to be tethered to a wifi to get things done.
Wireless connectivity is almost ubiquitous at this point. I have high-speed connectivity at home and at the office. The era of the desktop computer is rapidly drawing to a close. The cloud is obviously supplanting it. I wouldn't be surprised to see the desktop PC completely replaced within 5 years by a tiny Apple TV-sized box you plug into your monitor. It'll communicate with whatever other devices and interface gadgets (keyboards, mice, motion control, voice) you happen to have on hand, and with your cell phone and tablets. It'll sport advanced voice control, like Siri but far more capable, all powered by the cloud. It'll do games too, via a service like OnLive, and media, and if you want to run high-end software like Photoshop that'll be available to subscribe to for $20 a month if you're a professional or maybe $5 for a one day one-off use. It'll all be running on incredibly powerful virtual machines out in the cloud, so folks won't need to blow $1,500 every few years upgrading their computers to run the latest & greatest software. You'll buy a $200 Apple TV like box, a phone and a tablet or whatever and subscribe to whatever level of service you require beyond that.
Ubiquitous connectivity changes everything. It's essentially headed toward Star Trek technology, where you say "Computer" and tell it what you want it to do and it does it. "Computer, book me a flight to Boston on August 23rd. I can't spend more than $350." "OK, do you want an exit row seat like you usually request? And I won't search United because you hate them."
Also, shifting processing to the cloud offloads a lot of battery burden from these increasingly tiny mobile devices, saving power for their wireless radios. In the business world, it gets companies out of having to pay the Microsoft tax every three years and deal with the hassle of swapping out expensive machines. If everything lives in the cloud, managing the dumb terminals becomes a lot easier.
