Look at the context. Starting with an article about consumer model notebooks being slowed down by extra software being added by the maufacturer, you submit that Macs don’t suffer from this, and offer as proof the fact that you’re working from a Mac right now running 20 apps and don’t notice any performance degredation....a server class machine with 9 gigs of ram.
That's right at the moment... when I first posted, I was posting on my home machine... an iMac. Core 2 Duo, 27 inch, 4 GB DDR3 RAM. Not a server class machine at all. . . and I regularly run up to 20 major apps in four to five virtual screens with no noticeable performance degradation. I stand by that.
You don't run Macs so you don't have the experience to compare your PC experience to. You assume that what you are used to is the way it has to be. It doesn't. There is a reason why people who switch from Windows to Macs say "Once you go Mac, you'll never go back." That's not a slogan written by Apple or any ad agency. That was coined by switchers.
