Before the latest generation of MacBook Pros, how many laptops had 6hrs+ battery life? Any notebook with 9cell battery.
Before the iPhone, how many all touch screen phones were there? I had one that came out over year before the first iphone.
Before the MacBooks and MacBook Pros, how many laptops had chiclet keyboards? (I realize that sony did it first, but look how well that took off...) Who cares
Before the MacBooks, how many laptops had man sized trackpads? moot
Prior to the last 3 years, how many All-in-one desktops were there? moot
Before the Mini, how many external DVD drive sized computers were there?
Honestly, the only areas where the competition doesn't straight ape Apple's design is MP3 players (except for the Zune). And look at that market.
Apple steers the market. Hell, look at the HP Envy 13 and 15... they are practically MacBook Pro clones! Look at all the netbooks and laptops with backlit keyboards and edge to edge glass bezels, heavily rounded corners and apple style hinges. Actually take a look at the market and see who is influencing who and then tell me that Apple hasn't changed the tech world.
