Anyone went to MWSF? PB questions?

Hi, How was MWSF? good? I just saw the keynote over the Internet. I want the new 12" G4! looks awesome!


1) I believe 12" PB supports monitor spanning through VGA, but what is monitor spanning? is it the same as dual display support?

2) The new cases is Al, does it run cooler than 15" Ti?

3) Is the fan of the 12" PB loud? (its kinda hard to tell in MW since its a noisy enviroment)

4) I know Apple redesign thier product every 2 years, so this the new re-design PB for the next 2 years?

ohh yea.. the 12" PB lacks L3 cache, how big the difference with No L3 and 1MB L3 cache? like 50% increase in speed?
