Thanks in advance for any help. I have been trying to wait to buy a new mac until the core i processors are standard. However, it's getting hard to wait any longer and I want a desktop computer to use while I study for the CPA exam. Also, when I buy a computer I want to use it for atleast 4-6 years, I am still using my 12" PowerBook g4 1.33ghz I bought 6 years ago. Am I going to be fine for that time period if I get the base 21.5 core 2 duo iMac? Or am I going to be kicking myself in two years? I use my computers for safari, iTunes, Microsoft office (not heavily), watching YouTube and trailers online, and other iLife suites. I am not a power user by any means, but I use a variety of programs over time. Any help is greatly appreciated, and I am typing on my iPhone quickly at work so sorry for any grammar mistakes.
