I know it will have a smaller jump, but it will be a bigger jump for me if i skip the SB...IF I SKIP...we'll see if I can resist the awesomeness.
I also started checking out 17" MB Pros recently, so maybe....
indeed, these new machines are very nice, but depending on what you already have they may not really be necessary. Unless you are wishing your computer was faster right now, I'd hold off on upgrading until you feel that your current mac is too slow!
I'd be fine if they just announced it for pre-orders. Even if it doesn't actually ship for a few more weeks. I can dream.
apple typically only allows pre-orders on new products after a press announcement. With the last mbp refresh apple just refreshed them, didn't hold any type of event or allow preorders, the iMac refresh will likely be the same!
