Hello All, I tried to re-certify my Desktop Technician and Portable Technician Certifications over the weekend, but I failed them. I struggled in one particuliar area. There were several questions that were layed out something like this... What new feature was introduced with the iMac (Mid 2007)? A. Glass panel over LCD B. SATA Hard Drives C. FD-DIMM memory D. 802.11n There were like 6-8 of these type of questions with various apple products. Does anyone know if there is some sort of chart out there that shows the different versions and what was added to each or what was new? I got my certification almost 2 years ago. Re-certified last year but then quit as an Apple Technician so I've been out of the loop for about a year and it's much more difficult this year...having this layed out would be great. Anyone?
