The greatest computer moment I ever had was firing up a 24" 2007 iMac. The combination of OS X ( leopard I think ), which for me was the greatest leap in user experience ever, and the design just made it a 'wow' moment. It was a night and day experience from any other computer I had ever seen or used. 8 years later I have just taken delivery of a ( late 2015) retina iMac and the 'wow' factor just isn't there. Not much has changed. It's almost identical except for screen resolution and speed -- 2 things which are natural technological progressions and not apple related. The last 'wow' factor I had was when I changed my 2007 iMac HDD to an SSD a couple of years ago -- The speed difference kept the 2007 imac going strong until just a few days ago. I suppose the question I am asking people, is if they think iMac has stagnated because of technology constraints, or because Steve jobs isn't there anymore? I ask this question because 8 years before the 2007 aluminium iMac, Apple revolutionised the CRT desktop with their multi coloured 'bulbous' machines ( I owned one ), but 8 years after the 2007 aluminium no revolution has happened in both design or operating system.
