Hello- My current main computer is a 2008 MBP that is gradually failing or I should say dying a slow death. Teaching several grad courses online, a laptop computer is a necessity. I was going to go with the rMBP but thought a better bet for now wold be a well configured MBP. I was surprised that I can't configure it with more RAM. With the web platform and the programs I need to install so that the teacher's version of WebCT works, I need at least 12 gb of RAM. The dedicated graphics card is good, the HD is OK, but I do not have the knowledge to get the RAM and install it myself. I would not even know what type to get so that it matches what is already installed. I have to be ready to use an ethernet cable in case I lose my wireless connection during class time. We do have one day a week where we all meet in a virtual classroom on the WebCT platform, and I can tell who is there and who is not. anyway, in looking at my options in configuring a new MBP, I am disappointed that there are not better options. Does anybody have any idea how much RAM the current MBP can hold? I could see if the Apple Store would fill all the available slots for me with RAM. Just disappointed right at the moment. The rMBP is an option but to risky given that I need a higher degree of reliability with the notebook I decide to replace and be the main machine I use when I am teaching.
