$100 price increase. Increase in base RAM by 256 MB, but less than that in reality, considering the now-integrated graphics, meaning the RAM has to be shared. Yonah CPU, great. More USB ports, that was definitely needed. Nice that they included the audio input this time. The Core Duo one is a $200 price increase from the previous "high-end" version.
iMac is a much better package overall. I'm not very enthused about this one. I hope the iBook replacement turns out better (dedicated graphics
please).
