Just wondering if you guys installed OSX from the disk the MBP comes with. I'm reading that this is recommended because apparently Apple installed the wrong version OS onto the 17" MBP. Is this true? I already got rid of the printer drivers and languages I don't need manually. I'd rather not do a clean install as I already have most of my Apps and information on the laptop, but if there's a legitimate reason to do so, then I will. Any input on this?
