I'm thinking about getting an iMac and I've been waiting for this for so long but I couldn't afford it and I was waiting for my windows computer to stop working. lol. My windows computer has been acting up lately. Sometimes it doesn't want to start and it just restarts over and over, there are times when I turn it on and the moniter has the orange light which means its not getting the signal and sometimes the computer turns off out of no where! I have had it with this computer and I can't wait to buy an iMac. I'm so tempted to buy the refurbished 20 inch 2.4GHz iMac but the only thing that keeps telling me not to get it is the hard drive size. I want at least 500gb because I take a lot of pictures and record a lot of video. I have read that some refurbished iMacs come with a 500gb hard drive is that true? I have also read about the 20 inch moniters not being as good as the 24 inch? What's the difference between these two? I can't wait to own my first iMac.
