intel releases T2700 2.33 GHz Core Duo
The new Yonah-family processor could be used in a silent update of both the MacBook Pro 15" and 17" models. Then again, "Merom" (the successor to Yonah, which will bring ca. 20-25% more performance at the same energy consumption level) is not so far away.
But this is one of the things I'd like Apple to do: Update the MBP now and release the Merom-version when it's ready. Basically: Everybody wins. Apple sells more first generation MBPs, because the features go up one more time near the EOL, and customers would get what's available on the processor market.
If you own a Mac mini core solo, this new processor could also be the way to go when Merom comes out. I'm sure the highend Yonah will drop in price, once its successors are out. Still, a dual core 2.33 GHz processor sure would make more of that old 1.5 GHz single core Mac.
