I just wanna say that I use my iMac everyday, I never turn it off except under very rare circumstances and I always make sure that its up date. After 3 years of constant use and constant power, it still runs so perfectly well and I am astounded. I don't do much except for browser the web, listen to music and occasionally make and edit movies, yet it still runs so smooth and so brand new that I am still in love with it. My concerns were that as newer operations systems come out and more updates get released to software, my iMac would become less and less obsolete due to the lack of power - It is only running a C2D. However, so far it has not been the case, and if anything dare I say, it's running even faster then it use to! There is no point to the thread except to hopefully boast about how great these machines are and encourage new buyers to make the plunge, you will NOT regret it : ) Thank you!
