Forgive my ignorance, but I have a couple of questions about the WWDC. I'm planning on buying a macbook before August (I have to have it by August for school). First, does anyone think there will be updates to the MacBook that will be revealed at the WWDC. Second, does the new information about subnotebooks likely effect the chances of Santa Rosa updates in the MacBooks? Third, if there are any updates, how long does it take before those updated MacBooks can be bought? Will they be available in time for me to purchase one anyway? Thanks for any insight you might have!
