I purchased a Sony Vaio VGN SZ120. It has a great balance of portability (4lbs.) and power (2 gigs of RAM, Intel Core Duo processor, Vid Card with 128mb of dedicated RAM). The two main negatives is the price and that in order to achieve the 4lbs., it is quite fragile. That being said, it has a built in camera, and more impoprtantly a built in mic, which integrates well with MS One Note. With this I am able to record my lectures and they sync up with the key strokes. When I am unable to keep up in class or unclear on notes I have taken, I click on them and am able to listen to that part of the lecture again...this has proven to be extremely valuable. This is the machine I would recommend if you are willing to spend the money.
Dell's have sucked for awhile but Dell has recognized that their customer service and overall quality was becoming a bigproblem. They have indicated that they are going to go strenghten these weaknesses and so you may not want to write them off yet...just
something I have heard.
SMU uses exam software that is not Mac compatible. I would think long and hard before buying a Mac for law school.
