Hi, Thinking between MB and MBP. If I wanted to add the 128GB SSD in configurator, would that be a mistake or not? There's a lot of discussion about SSDs here, but I am confused. I want the OS to run as fast as possible, with the least heat, vibration and weight. I think SSD is the way to go. But I don't want to order it separately and install myself. Is the Apple-offered SSD 128Gb for current MBP an OK drive? Thanks!
