That's right, I have a few questions. Just in case it is useful, here are the specs for my machine: 3.4GHz Quad-Core Intel Core i7 4GB 1333MHz DDR3 SDRAM - 2x2GB 2TB Serial ATA Drive+256GB SSD AMD Radeon HD 6970M 2GB GDDR5 MAGIC TRACKPAD-AM 1. Is there anything essential I should do when I boot up my iMac for the first time? 2. Will the iMac come with the OS already installed on the SSD and the 2TBHD empty? So, all my applications will already be stored on the SSD? 3. What should I use the SSD for? What files should go in there besides the OS?
