I got my 20" iMac G5 today and I love it. It is totally quiet. I haven't heard the fans come on at all (is that a good thing? ) This is my first apple product, so I am learning all new things. I am, however, typing on it right now, so I must be doing okay. I have had one glitch, however. I downloaded a pdf of my most recent bank statement, and all 4 pages are blank. I can't see a thing, but the pdf viewer is acting like there should be something there. Any advice? This screen is bright and beautiful.
