It’s a software mixed world. I use a Mac but work mostly within Google Chrome. Remove the Mac and I can pick up where I left off on Chrome even on the shoddiest of PCs.
Software is mostly agnostic. But I think hardware will head that way too. At some point, the phone itself will be cheaper and all the money will be in services like apps and social networks.
The phone is just a remote control for the Internet. Like a car, its true value is getting you from A to Z. There will always be phones with better camera, audio, and screen features but the phone’s basic utilities are sufficient.
Once we’re all connected to the Internet water fountain, the hardware becomes secondary and sharing digital content becomes the most important thing.
