Hello, I will be attending university next year to study engineering and I need a laptop that will help me in my studies. I just have a few questions about what type to get because I have no idea and I thought the professional engineers or students still studying engineering could help provide me with some insight. I am very curious and intrigued about switching over to the Mac OS. One of my concerns is the compatabilty with programs and software that studying engineering requires. Have any of you engineer mac users ever had problems compatabilty of programs? Another concern about switching to the Mac OS is that while working as a an engineer do you ever use the Mac OS? I would assume that most, maybe all, engineers use PC's but I do not know. So, any tips, suggestions, or reasons on why I should or should not switch to the Mac OS for engineering? Thank you for your responses.
