Appleâ€™s post-PC vision isnâ€™t about input devices â€” mice, keyboards, pens, whatever. Itâ€™s about exposed complexity.
Apple simplified and the result is less complexity. Windows 8 is still complex, just like Windows 7, but Metro covers it. That’s the difference between post-PC and PC plus.
This plus suffix reminds me of the idiotic term “number one plus”.
