So here is my dilemma... Currently: I use a combination between an ipad 2 for portability and at my desk, I have a 2010 15" macbook pro i7. I have my MBP connected to a LED apple display and use it in clam mode with an external wireless keyboard, trackpad, and bookarc. I use the MBP for serious computing such as CS5 and ACAD and can't downgrade my power because I will be using these processor heavy programs for the distant future. I like my MBP but I don't seem to ever bring it out of my apartment(class) since getting my ipad. I think i am wasting the portability of the machine and sacrificing some of the performance because it is a portable machine. I want to sell(or hopefully trade) my MBP for a Mac Pro. Most likely, a 2009 model, because i could use all my peripherals with that one. I feel like the MP will last longer and have sufficient performance for some time with the user upgradeable nature of the machine. I could then use my iPad as a portable device and would consider purchasing a 2011 MBA. Am I thinking logically or am I just getting bored with my current setup. In which case, I would just suck it up. What do you think? Is a MP with an iPad and possibly a MBA too much for a college engineer?
