I just wanted to present the question to those of you who have been using Macs for a while on how long they typically last? I know each case can be different and perhaps the type of computer can come into play, but I am thinking about purchasing a Mac and I want to be sure that it lasts for a long time. I have been a PC user to date and I have had a chance to try out the OSX operating system. It seems pretty good but I also know there is a lot of things I don't know how to do because I am use to Windows, not OSX. Anyway, I built my own computer about six years ago. Here are the specs: Athlon 64 3400 2 Gigs of DRR Ram 250 SATA 7200 Hard Drive Geforce 6800 Video Card Windows XP This computer has lasted me a long time and its still going strong. Now, I will admit I have had to reinstalled Windows XP numerous times over the course of six years because of the areas that can plague the Windows operating system. I usually use AVG to combat any viruses and I would say I reformat every 9 months to possibly 1 year and 1/2. During that time though, my computer really isn't slow and doesn't bog down too bad. I have also taken the time to clean out my computer when it comes to dust. I have dismantled the CPU before to get dust out of the heat sink so it can properly cool my computer. I have also cleaned out the video card fan at least once during this time to get it cool as well. The computer is still great and suits my needs really well. Although its six years old, I have a hard time justifying to buy a new computer because the hardware is still running with no issues. I guess proper maintanence has made the difference. So my question is, do you think a Mac will last this long? I see posts in many areas where hard drives are dying or the computer is dead after three years. I can't help but wonder if the user is giving proper maintance to their computers like cleaning out dust so that fans can run properly in cooling their systems with the heat and all. Anyway, I am not trying to start a debate on Mac vs PC. Macs are great. Just wondering what your experiences have been. Thanks.
