I'm going to get the 27" high end iMac, but not sure if I should buy the SSD along with the HDD, cause I've read somewhere that the SSD model in the iMac is not a good one compared to other SSD's. Is this true, and if so, how much in speed difference are we talking compared to the "better" SSD models? And is it likely or even possible that the OS will have an update soon to support Trim? (not even sure what that is, I'm in deep water here) And is it true the life span on an SSD is just going downhill when it comes to performance, or is that just some models? And is that over a 2 or 10 years cycle, and how much in % are we talking about? Ok it might have to do with how much one use it of course, but is that only when one re wright data or just for accessing data? This is the only thing that's keeping me from buying this iMac this sec, and of course the concern about the amount of iMacs returned by users due to the screen problem. I don't wanna throw 1110$ (Swedish store) down the drain. Would appreciate answers, best regards (oh yeah, my fake name) Raul.
