I'll not be satisfied with any computer likely to be developed in my lifetime. Three simple requests:
1 - Turn it on and off like any other piece of electronic equipment. No more booting, loading, configuring, initializing, scanning, analyzing ...every time you turn it on. No more "shutting down" (walk by five minutes later and still see a blue screen, "shutting down").
2 - If computers are so fast, and getting faster every generation ... why are we always waiting on them to do something? When "Please wait" and "Loading loading loading" are relics of ancient technology, I'll be happy.
3 - Microsoft, you have had thirty years to develop windows. You brag of how "fast" and "efficient" it is. Bah! I am not impressed that your system can juggle a trillion terabytes of data every nanosecond because the fact remains that if even one byte of all that is corrupt the entire system collapses like a house of cards in a hurricane. Please, develop a fail safe OS.
