So it's been a while since I last bought a Mac. I bought a 2006 MBP for college and should be receiving my new retina MBP from FedEx shortly. Since I've been out of the loop with the hardware over the years, I do have a few questions. Having an SSD is very new to me. I've never had a machine with an SSD before. Is there anything I should do to take care of the SSD? I hear they have TRIM enabled by default, but other than that, is there anything I should know about using one? Also, in terms of the battery...I use my current MBP like a desktop now because the battery died only like 3 years into its life. With this new Mac is it ok to leave it plugged in while I work on it? I'm always afraid keeping it plugged in even after 100% will affect the battery life. Am I crazy or is this not an issue anymore? Sorry if these are stupid questions, but you have to realize I'm coming from a C2D maxed out at 3 GB of RAM with a 120 GB HDD. so it's been a while since I've had new hardware. Thanks!
