Given the new 4K 21.5" iMacs scored a 1 out of 10 for repairability from iFixit with user upgrades now nigh impossible are these new iMacs worth having? I think they are not. The end user now has to make a decision whether to load it with upgrade options at the time of purchase, paying through the nose to do so with no upgrade options further down the line. One wonders how long it will be before the 27" becomes similarly crippled. It's very sad that Apple have decided to virtually seal these units thus excluding the enthusiast from them. It's definitely a sign of the times and I accept that lots of people will pay the asking price. However, if more people walked away then Apple would have to rethink this policy.
