The MacBook changes, some for the good, some for the bad. First the good – the unit comes with a 2.26GHz Intel Core 2 Duo processor with 2GB DDR3 memory, a 250GB hard drive and 8x double-layer SuperDrive. The graphics cards is still a GeForce 9400M graphics card but the battery has been bumped up to a built-in 7-hour battery placed in a new polycarbonate unibody enclosure. Now for the bad news – FireWire connectivity is gone from this model. So if you have any FireWire devices that you use you will have to replace them with a USB device.
