Think about how different Ubuntu is now since then. Windows 8 is a real risk-take from a company that does not take risks (whether they were forced to do so or not is another argument). Mac OS X is... Mac OS X again.
I've been using Mac OS X since 10.2, and I will get another Apple machine for my next one, but I really don't know why they bother putting anything out if they're just going to phone it in each time. Pretty much everything added to Lion I really don't care for, and what they did add was minimal anyway.
I wonder if they really have the vision and the tenacity to actually move things forward, or whether iOS and Mac OS X are going to remain the way they are until the company can't take it anymore. They need a software person like hardware needs Johnny Ive. Someone to put their foot down, say "we're doing this" and follow through.
The next 10 years of Mac OS X cannot be the same as the last 10 years, can it?
