The writing is on the wall… I am just going to put out there that I bet that in 5 years, many many many more people are going to use the internet/web/etc via phone/tablet/smartphone (whatever you want to call it) rather than laptop or desktop. Those things are going to go away and we are eventually going to transition back to more differentiated products. So maybe you will need a “normal” Windows or Mac or linux machine with full on keyboard, etc for writing and “spreadsheeting”, but for shopping/emails/facebook/MP3 listening/photo taking/editing/organizing/video game playing etc…. those machines are not important. A smartphone is fine. Or will be.
And in 10 years, none of this may matter. By that point the important skills may be local local local: farming, canning, sewing, piano playing, etc.
