I'm waiting till the 15th before I decide which notebook to get for live/studio music use (Logic Studio mostly). As long as the new MB graphics card is able to run Mainstage (apparently they can't currently), I'd like to get one of the rumoured ultraslim MacBooks for portability/money/coolness But, the one thing worrying me is the rumoured 64GB flash HD. How would this perform with Logic compared to the MBP 5400rpm standard HD? And, approx how much space does a normal Leopard install take up? Thanks!
