I'm reading a lot of people are comparing MBP to VAIO Z and also some others even with MBA. So I checked some features and if I'm not wrong both comes with i7 and GT 330M(1GB for VAIO and 512MB for MBP). Another hot topic is the VAIO as 6 Hrs battery life vs the 8 to 9 of the MBP. One more thing is that the VAIO is dearer than the MBP. Do you think one is better than the other, or one has some better feature but some worse, or they are more or less equivalent?
