From First Today, Then Tomorrow:

How will this come about? Hardware, for what it is, will sometime soon become irrelevant. Your will have secure access to your personal data and your media from anywhere you are. You may buy a device, like a phone or a tablet, but they will be very inexpensive, almost disposable (and certainly recyclable). There will be no benefit from buying newer hardware. It will not be faster or have more storage. It will not offer new features. All that will matter is the software and the net and the net will be everywhere. For that matter, the word “software” will fall out of fashion. You will have apps, you will use features and tools. You will also stop using the word “computer.”

Sounds pretty possible to me.
