Now before these two palookas start mixing it up, here's what they bring to the fight. The
MacBook Air is the cagey vet. It has improved with better processors and an honest-to-goodness graphics card, nVidia's GeForce 9400M, so it can actually play
some games. The Air we last reviewed offered a 1.86GHz Core 2 Duo CPU and 2GB of RAM, and scored a 78 in WorldBench 6. In our battery-life tests, the Air survived for about 2.5 hours before sputtering out. It can accommodate a 120GB hard disk. But then there's also the dreaded "Apple Tax": These machines range in price from $1,799 to $2,499.
