I realize that this iMac is super expensive and was approaching Mac Pro territory. I got it over the Mac Pro because it comes with the 5K monitor and the new keyboard and minimal extra for the new trackpad. The screen is amazing. My boyfriend has the 2014 iMac Retina base from before they introduced the lower priced iMac Retina. It looked amazing but it looks even better on mine because it's for me to use. I know that sounds silly but it's true. The first thing I noticed was just how sharp it is compared to my 1080P Dell monitor I have sitting next to it for my Mac Mini. That monitor never looked bad right up until I powered on the iMac. Now it looks blurry in comparison. I like the new trackpad a lot. It is a huge improvement over the previous version of the track pad. I can even use it on the couch now to drive my 2.5GHz 2012 Mac Mini in the living room for web browsing and stuff beyond the Apple TV 4's capabilities. That has got me thinking I am going to buy another trackpad specifically for the living room. The new wireless keyboard has more clicks keys with less travel. I don't feel the membrane under the keys anymore. Interestingly enough it's almost like a mechanical keyboard because the lack of travel doesn't require as much pressure. I say almost because there is still the issue of impact on the keys because you have to press the keys all the way down to register but since you don't have to press as hard anymore the effect is noticeably better. I opted for the 1TB SSD because of the uncompromising speed of it. Because there is no (Corrected)7200 RPM drive I don't have to have some programs start instantly and some that bounce a few times before starting. It provides more consistent speed. My 2.3GHz Core i7 Mac Mini has a 250GB SSD as the SSD portion of the Fusion Drive. It handles the slow down issue a lot better then the 128GB that Apple sticks in their 2TB and 3TB Fusion drives. I would probably been willing to go with a Fusion Drive if it where at least 250GB in the iMac. Since I can't open the iMac without voiding my warranty I decided to spend the money now so I am not spending more later trying to upgrade it. The sound of the fan in the iMac is more noticeable in the iMac then the Mac Mini but of a lower pitch. I'm not sure how exactly they did it but the sound of the fan is not as aggravating as the sound in the Mac Mini. That is saying a lot because the Mac Mini fan sound wasn't bad to begin with. I can't say enough how awesome this machine is. Anyone here that knows me knows I love my 5930K machine but I'm going to have to upgrade it's monitors to some curved ultra wide screens in order to be able to look at the image output after seeing this 5K screen.
