I'm ordering my MBP in about 12 hours time and I'm not sure which route to go down. I am ordering a 2.2ghz 15'' AG. I have 50GB of music, I want to install OSX and Windows 7. I have 1000GB of videos but they don't need to all be on the laptop. Do I go for: a) 750GB @5200RPM b) 500GB @7200RPM c) Apple SSD 128GB (for £80) I was leaning towards the SSD and having a USB harddrive but in reality, does having all my stuff stored on an external USB drive defeat the purpose of having an SSD? Does an optibay void your warantee? I would consider this if it didn't mess with my apple care.
