What do I invision as the future of computing? Nothing but dummy terminals. We can do our banking, gaming, chatting, everything from dummy terminals.
Cheap and mass produced, every home will have one. with a mobile version for all.
Just think, your computer is nothing more than a 30" 5mm thick OLED with a discreet keyboard. The mobile version either being in a cellphone/tablet fashion, or a more direct accessory, such as a armband with a thin, light, durable and cheaply replaceable touchscreen.
Were we no longer have to worry about updating, upgrading, anything. You want to play Crysis on your phone? Then do it. Servers in every city to handle anything requiring low latency, and international servers to handle the heavy stuff.
Maybe I'm just crazy, but I see a world were everyone has what they need. No worrying about whether you should spend $500 or $2000 on a laptop, if it breaks whether or not you can afford to fix it, no worrying whether your phone will run that app for you or not. Were you don't have to cancel your internet just so you can afford groceries when times hit you hard.
A world were everything just works.
I'm shooting for the stars, how about you? Microsoft and Macintosh have enough power and money to help us a least start the changes, but without their support, it will likely take 50 years more or just never happen.
