I have used iMac for over 20 years. Still have my G3, last of the PPC iMac and currently have two 5k iMac - 2017 and most recent. The ”all in one” so I could have one cable and all ports not sticking out at odd angles was a feature I liked. Recently the lack of user repair and upgrade has concerned me - at least I could add memory and avoid the “Apple Tax”. The new iMac has led me to reconsider. I tried the Mini and had wake issues and Bluetooth issues so it went back.
I am evaluating the Dell Optiplex 7090 and it is a very smart idea. When assembled it looks very minimal. The option to choose stand, Monitor, processor module and have it all in the one unit is compelling. All can be easily changed. What also struck me was how serviceable the computer module is. Dell even make available a detailed (circa 70 pages) service manual showing every aspect of dismantle and reassemble. Many components are replaceable with off the shelf (memory, NVMe etc) or Dell specific parts (fans and so on). Dell even make the parts readily available at decent prices.
I spoke to Dell and explained my dilemma. I was advised to try one for a while and was given an extended return period. I have the highest spec i11 with 32GB and 512GB. Using the pro stand and have Dell 4K USB monitor attached. Dell sell it in UK with on-site next day warranty for less than entry level 24” iMac if pushed.
So far I am very impressed. It looks superb. It is also height adjustable with tilt and rotate so ergonomically it is superior. Matt display is welcome. One cable and very silent. Add on the upgradability and it is compelling.
Until recently I never looked beyond Apple. Lately the lack of repair, cost rises, odd design decisions (from my perspective) and various issues with software that were eventually admitted bit never resolved caused me to feel a little restless. I was for many years a confirmed sale for Apple. Now it is not so assured.
