EDIT: Yonah is the name of the chip inside all the Intel based Mac's, just to clear the confusion. Just as I freaking thought. To every one of you guys who thought that this new chip was going to blow your socks off, you'll be disappointed. To those of you who felt you have Intel based Mac’s with yonah's inside them, fear not for your products are marginally slower at best.

What are you going to do with your intel mac all day? Calculate integers and pi to 30 million decimal places? no! So for anyone who was waiting for this chip to come out, I don't see what the big deal is. In my honest opinion this chip won't get all the credit it deserves until the new Santa Rosa platform launches in the first half of 07. To those of you who want to know what Santa Rosa is: source: http://en.wikipedia.org/wiki/Centrino#Santa_Rosa_platform info: Conclusion: If you have an intel based mac, be happy, you're far far far away from being considered out of date. If you've been waiting for the merom before you buy your notebook, then you're just burning your time.
