64 Bit support! Sure there are ways to reduce (for example) exporting of heavy models, but using the full 16 Gigs on my system would surely help to avoid the ever-occuring "Insufficient memory" error, or not? Not really sure of all the actual pros/cons of a 64-Bit compared to a 32-Bit. But is that really a question these days.? 64-Bit is eventually the way it will have to go anyway. Or is there a reason to hold out?
