Comments about Apple 21.5" iMac Desktop Computer (Late 2013):
I upgraded from a iMac Intel Duo so this is def a lot more machine. The description said it was a "free upgrade" to Mavericks and I assumed it would come with M Lion and could be upgraded if i chose but it came preloaded with Mavs so be it. Seems to be a pretty good OS so far. Haven't had it long enough to have formed an opinion on the Fusion drive but the boot up doesn't seem to happen as fast as my Macbook pro with an internal SSD, not sure why that is. Wish it had a FW800 port as I still have peripherals but the Apple FW to T.Bolt cable does work fine. Only $ so no biggie I guess. Also no CD/DVD drive on these so cough up another $ for an external. Comes with keyboard and mouse.
Bottom Line Yes, I would recommend this to a friend
