Alright--I had my parents' credit card all ready to go for the PDF, but it wasn't ready, so I'm reduced to begging y'all with SR4 experience to enlighten me.

How exactly does the Matrix 2.0 work? How effective are deckers (I will under no circumstances come near the "other" term for computer intrusion specialists--bwa!) versus technomancers? Is it still set up in a LTG/RTG/PLTG fashion? Can you still actually get into systems, or do you have to have a physical presence near their computers? Etcetera.

Really, any information will be appreciated.

Oh yeah, and one big question: Is it better or worse than previous SR games' Matrix systems?
