MacBook Pro, all the way man. You can't go wrong, especially if you are a designer. I am a designer and I use a PC so I can run my Wacom Intuos pen tablet....if you dont use equipment like that then the MB pro really is nice MacBook Pro is the way to go.
Personally, I would get a macbook pro. I have one (the 13 inch one) and it is really good. I really didn't like the macbook white being - white and I didn't like the shape either. I know that macbook pro's are more expensive, but you could use a student card to get a discount and if not I still think that they are worth it. But that's my opinion.
you probably should get the MacBook. they are cheaper than the MacBook Pro. now, if you want a bigger screen, then get a MacBook Pro.
The Intel Core i5 offered in a new MacBook Air is more than sufficient for daily use. A MacBook Pro is better suited for heavy design or developing use.
Shell programming can get you only so far; after that you need to use another programming language (possibly even another scripting language) to get the job done. Shell programming is designed to work with the system interface and to help automate tasks; it isn't good for everything.
It depends what type of engineering you want to get into. Electrical engineers will use programming.
