The difference between a computer and a consumer electronics device is you expect a computer to crash once in a while. However, while it may happen, you don't expect your phone, gaming console, GPS, or alarm clock radio to ever crash. While most people have and tolerate computers, a large majority would be better served with a consumer device that can handle most of their computing tasks. What are the rules for this device? 1. It can't EVER crash. Locking down the OS would be essential as all software and hardware must be integrated perfectly. This means all apps must be approved (like through the App Store approval process). 2. Minimal tech support required Don't you get frustrated when your mother has a problem and calls you to fix it? And I'm sure she's more frustrated than you. Time is money. Even a minute of tech support (or scouring the internet to find a solution) is a waste of time. 3. The user can't do anything to degrade performance or harm the computer. This includes accidentally deleting essential files or messing up the OS. This also means no multitasking (or better yet, controlled multitasking). People can't be allowed to slow down the system in anyway. This also means no flash until Adobe fixes the bugs. 4. It should require minimal computing knowledge to access all features. Time is money. Time spent learning how to perform a task is time wasted. Now, OS X and Windows will not disappear and will still be necessary for people who need to do more advance tasks but if the iPad can offer a basic consumer computer for the masses while removing the frustrations of traditional computing, it will be Apple's biggest success.
