In my first year of engineering the programs didn't seem to demanding, though I don't know what programs your college will require you to run in the first year. A slightly more powerful laptop may be beneficial to have for the programs you will need to run in the following years, though that may depend on whether the college wants you to be able to run the programs in class or whether they will provide computers to use during the class. If the classes that require more demanding software provide computers in class, along with you owning a decent pc, you could get by with less as far as the laptop is concerned. I would advocate that the precision 5520 served me well last year, providing excellent performance along side a portable form factor, but the price is somewhat high, so I would not necessarily say that is the right choice for everyone. There are less expensive computers capable of running the programs adequately enough. I personally have never liked Apple's pricing, design, or user interface. If I were recommending a computer for engineering, it would be a windows machine, but I would not necessarily say there aren't Macs out there capable enough to use for engineering, and for some people who really like the Mac interface, it could be the right choice.
