I look at the Apple/Microsoft arguments & conversations the same way I look at the Xbox/PS3 arguments & conversations. If your really that immature and selfish to apply some fake allegiance, blame or too much credit to either side, please...go home tonight, lock yourself in a padded room and listen to 80's pop radio for 2 hours.
Both companies have been instrumental for the industry. The way I would word it is, Apple has had more motivation and reason to succeed in the past 10 years because they were in rough shape. Microsoft however has sat on thier hands more because they haven't need to R&D like Apple has. These are just natural aspects of large business and market control.
I wouldn't say others were too lazy to innovate, I just think Apple was extremely motivated to make products people want again.
And to the comment above mine... Apple is in a 'slump'..... really? Now? I would like to think Apple is doing quite well right now, maybe not so much with mainstream PC's and workstations, but that will come. You get someone to buy a pencil and they like it, next thing you know they want the whole desk.
