What about simply rational? It's easy to become excited at the prospect of shiny new merom macs ready to hit store shelves tomorrow or tuesday, but I think that's premature. The rational part of me, which has taken over the part of me that's flipping out excited, says we'll see them within three to four weeks. I know that's disappointing to a lot of people, but if you have read through these posts, and the macforums front page, I think it's easy to surmise that that will be the case.

But don't be fooled by my rational side too much. I've already bought a .mac account and a cool new backpack to house my MBP when it finally does ship. I'm about ready to jump out of my skin I'm so excited.
