So i am new to the Mac, well i have been away for about 12 years. Big difference in HW from back in the day. So i ordered: ~~~~~~~~~~~~~~~ 2.16GHz Intel Core 2 Duo 2GB 667 DDR2 SDRAM - 2x1GB NVIDIA GEFORCE 7600 GT w/256 500GB Serial ATA Drive SuperDrive 8X (DVDR-DL/CD-RW) Aperture WL kybd, Mse & Mac OS X Country Kit ~~~~~~~~~~~~~~~ 1. Do i need to update sw, version, patches. YES YES YES YES, i know its not a windows machine, but that was my world last 12 years. I'll break the habit soon enough. 2. The keyboard. Is there an ergonomic version? 3. I'll take any advice at this point.
