Computers for University studies

I'm looking for a laptop to use for university studies.  I will most likely major in some form of Engineering.  Minimum specs for my university are:

2.0GHz CPU
512MB RAM
Newest Microsoft Office
Windows OS - Vista preferred, XP accepted.

I don't know everything about computers, but I know enough to think that those specs will not last for more than a year at that level of study.  Which computers would be best suited to last 3 years (I doubt that's possible but it would be nice) for an Engineering major? If it's possible a computer on the less expensive (<$1200 before any warranties) side would be nice.

What's the sound of one hand clapping? Just because you agree with yourself doesn't mean you are right.

Also, read "those who know least know loudest."  Similar principle: just because you keep repeating the same thing doesn't make it true.

Now, back to the reason of this thread, troll.  Why don't you use your self-proclaimed brilliance to do something positive, instead of filling your mom's basement with hot air?
