In my experience, laptops in a law lecture will be useless. Law lectures don't go for long, well a least in first year (i found ~half hour). Say for contracts, there is about 3-4 pgs of brief notes, they talk about the rules/structure and go through a few examples. All in all, the contact hours are tiny. Basically, to succeed you need to be the best at time management. Keep up with the material (readings), don't worry about making excessive summaries (you will fall behind), and hit those ASSIGNMENTS as soon as they appear. Since exams are open book, you don't need to know the CONTENT of the law in great detail; you need to build your statutory interpretation skills, comprehensive ability and legal problem solving skills.
IMO, studying law is highly unique compared to other subjects I have done- ie commerce. Commerce is much more about memorisation. It's what you expect. Long lectures (relatively easy material though), tonnes of concepts to know and multiple choice exams (a lot of the time). Much more 'HSC' style, especially in first year.
Hope this was helpful.
