Hi everyone - long time reader, first time poster here. I'm upgrading from my 2007 MbP (stolen last month), to my first 27" iMac when the new one is released, and have a query on the RAM and SSD options. It's primary use will be music production using Logic Studio and related processing heavy external plug-ins. Based on price and ease, should I simply get the standard 4GB RAM and 1TB HD offering, and upgrade to a higher level of RAM and a SSD after purchase separately? If so, is this easy to do and does it affect the Applecare warranty at all? Also, would there be any other upgrades or add-ons which would be recommended for this kind of use? Thanks very much in advance for any advice.
