I just got in a new Mac mini (i7) and started playing around with it. Massive improvement over my previous machine (One of the first intel MacBooks) and overall pleased. However. Both machines have 4gb of RAM installed, an while the laptop is running Snow Leopard, it appears that the mini is sucking up just shy of 2gb of memory the moment I boot it up - compared to the 700mb (or less) the laptop sucks up on boot. Is this normal?
