4GB....my thoughts
I was concerned about only have 4GB RAM in a machine as well. That was until this last week. I was working on a 16x20 photo in Photoshop and had 7 additional files in Photoshop from my D7000. Was making a poster for my daughter from our trip to Disneyland. It was the first time I have not had a Beach Ball of Death when working on a project like this. I'm coming from a MBP with 16GB RAM. I can honestly say the speed of the SSD more than makes up for the RAM.
Your mileage may vary, but I'm more than happy with the 4GB RAM.
