Hi All, I purchased the iMac last year as a refurb and compromised on the HDD at the time since there were no SSD options available. Now that my apple care is expired I've been thinking of taking advantage of the BlackFriday sales to upgrade to an SSD. Just wondering what's your recommendation, worth the hassle ? I'm in the IT field but don't use the iMac for much more then browsing the web and a bit of scripting etc... but I like a snappy O/S . The other question I have is around the thermal sensor on the 27". How do you get around that ? I couldn't seem to find any details on this on the web.... Appreciate the input!
