Sorry for not updating this thread. My concern is not the premium price alone, but are the iMacs really that price competitive today in real world? They need to do a reality check. After Steve Jobs died, to me, I think Apple is already in trouble with its marketing positioning, and they may NOT be able to survive in the next 10 years or so due to aging hardware, consumer awareness of their higher prices, more and more competitor sellers, and declining number of technology inventions. Look at their stock prices falling lately.
Back in 2006-2007 when all-in-one PCs were 3 times more expensive than today, and iMacs were at $200 starting price lower than today, it was more economically wise for me to choose iMac over a PC, and I was glad I bought one. Now the gap has widened today by 5 times the amount, and all-in-one PCs now start around $399.99 today vs. $1,199.99 in 2006, lately, it's no longer economical for me to consider another Apple computer anymore. I accidentally let Apple slipped out from mind and forget about them since the last 5 years or so.
And yes, I still have the 2006-2007 20" iMac white-plastic version today. It was a good value back then. It's now 7-8 years old and I don't know when's the right time to upgrade, and I fear I may no longer be a returning Apple customer. Money is not the issue here, but I'm always pessimistic and concerned all the time whether I get a good value purchase or not (2014 iMacs are not good value at all, sorry to say, and Apple is taking advantage of the extra greedy profits had I purchase one).
