So after much waiting and deliberation, I have just purchased a new 27" iMac. The model I bought was the highest stock configuration, 3.3Ghz i5, AMD m395, 2tb fusion drive etc. Originally, I wanted to get this config but swap out the fusion drive for the 512gb SSD, but for whatever reason my education discount was even more in store than it was online ($410 off vs $280). This meant that upgrading to SSD would have cost me approximately $400 more (after discounts), and that is not even considering the cost of a good external 2TB drive I would inevitably get as a media drive. I did this knowing that the apple store has a 14 day return policy so that if I found the fusion drive to be too limiting, I could always bring it back and get the higher model. Anyway, here are my impressions so far: The screen is beautiful, as we all knew it would be. I very fussy with displays, but the screen calibration is really nice, unlike my early 2013 rMBP which had an overly-cool white point straight out of the box and a gamma which was too high. The fusion drive has been good so far. It boots slightly slower than my rMBP (with upgraded OWC ssd), but launches applications noticeably faster. Black magic benchmarks it at about 700mB/s read and write, which is honestly a bit concerning as the new SSD's are supposed to bee much speedier than that. [EDIT] further testing suggests that read speeds are more along the lines of ~1500MB/s as others have mentioned with their new fusion drives. Performance is generally good, I haven't noticed any stuttering so far. The new keyboard feels strange. I have seen reviewers say that it doesn't have less travel than the previous wireless keyboard, but I disagree. To me it feels a lot like the keyboard in the new macbook. Honestly I kind of like the feeling, but time will tell if I keep using it or swap it out for something else. I am not a fan of the new magic mouse, just like I was not a fan of the older one. To me, the biggest problem is the plastic material they use on the top of the mouse; it's just not frictionless enough, and I could see myself really liking the mouse if it had a smooth glass top. Honestly my biggest complaint with the computer is that the bezels are just so large! I have a feeling that we may see a redesign when Intel releases Kaby Lake, and if that happens I will probably sell this one and upgrade; yet another reason why I didn't want to spend a whole lot on it. I will be keeping an eye on the benchmarks for the new ssd models. If they tend to be noticeably faster I might change my mind about the fusion drive, but so far it has been pretty great.
