SPECS: MacBook Pro, 15-inch, 2.0GHz Intel Core Duo 15.4-inch widescreen display (1440x900 resolution) 512MB (single SODIMM) 667MHz DDR2 SDRAM 80GB 5400-rpm Serial ATA hard drive Slot-load SuperDrive (DVD±RW/CD-RW) ATI Mobility Radeon X1600 with 128MB GDDR3 memory Built-in iSight Camera Front Row and Apple Remote I am just getting back on the forums as well as on a Mac. I have been using Windows for the past two years because my old mac broke and I've just been using a descently fast Windows computer and was busier with other things. My brother owns a 2.0 GHz Macbook. I know all about the Intel transition and this will be my FIRST INTEL mac. What kind of speed can I be expecting out of this computer now and in the future when more efficient apps are created? How does this chip compare to the G5? and how quick do the CPU's work together? In theory can it be a 4 GHz processor? Sorry for all the questions I am just so amped up about getting back into OUR culture. As well as seeing Steve Job's keynote in January!
