why would *I* move to the cloud? I have a laptop.
1) By virtue of reading slashdot, you are a geeky weirdo, not a typical user. You'll never want to move to the cloud, until you become like your parents. You'll be the reason Linux will become the desktop OS of the year (forever actually).
2) You can operate on the cloud with a laptop. Its called a chromebook. Yeah, for those who care, some form of wireless network service will be ubiquitous for urban areas.
Why would I move to the cloud?
To not deal with Microsoft's haphazard software security updates. For your data to be slightly more secure once you move to cloud computing. Because one day a cloud service will offer the average user advantages over standalone OSs, like unlimited, ease of use backup of data, better price for computing services than a standalone PC (which seems to need bimonthly updates), and the whole "system" doesn't go obsolete, requiring repurchasing every few years.
And after the majority of users have moved to cloud services, one day you won't be able to use your credit ID to buy stuff, because the vendors on the internet will only want to sell stuff through the "secure" cloud. The gamers have long ago moved to cloud, because its costs nothing to send a video stream to your screen, while the cloud has preprocessed that gamer stream with its 1M of GPU units per cents of gamer time, and the user will never have to dick around with buying video cards and video card settings. You remember how long ago, EA Sports stopped selling a version of Madden Football to PCs? That'll happen for the cloud as well for other games. Besides, no consumer discrete GPU will be able to manage the imaging for your hologram room, where you'll do all your gaming and visiting distant friends and relatives.
Only neckbeards, survivalist whackjobs, and Alex Jones fans will want to have their own computing box they "control".
In a foreign country with absurd internet costs ...
There will always be people who want to go to a shithole and have internet access. Those people will have laptops running linux. Normal (non-rural) people will live at home, and the cloud will be ubiquitous, and they won't even realize that wireless networking services will be required to get their "screen" to work.
Microsoft is motivated to do this, but right now, the business sector is the only customer that really grasps the potential ROI. Once they're on board and datacenters and APIs are in place, Microsoft will figure out cheap ways to absorb the consumer market. If they don't, some company in India or China eventually will.
