Tomm I will be unplugging my 30 lb imac, carrying it down two flights of stairs, nervously load it onto a cart, walk a block to my car, super carefully load it into my car, then drive half an hour, unload it two blocks from a busy mall and taking it into the Apple store, for the third time in two weeks . This is BS. First my logic board went bad, then my harddrive crashed, now it is getting a kernal panic every 15 minutes, and absolutely freezing to the point of hard reboot. I demand a new computer this time. Is there anything I can do to have them just give me a new refurb imac? This has been a huge hassle, and cost us a huge amount of downtime right while we are in the middle of a big project. I really can't afford for this to be broken anymore. Has anyone had luck with the geniuses just getting a total replacement, instead of chasing a problem they don't seem to be able to isolate? I am intending on buying a second imac and returning it if they need to keep it again. Sorry for the rant but this is the worst apple experience that I have had in the years I have been dealing with them. I am not specifically mad at the geniuses, and this could just be bad timing, but it really is time for them to just take my machine back, and give me a new one.
