I have been very tempted to buy an iMac. I have an iPhone and love it. I have been doing some reviews of apps for young children (dropped off a bit due to work commitments, trying to get back into it). I would love to have a crack at writing an app myself (even if I never released it). The price difference between the 21″ iMac and 27″ iMac seemed so small, I thought I would go with the bigger model.
Before buying, I thought I would do a quick search for news on the iMac. I mean, should not be necessary – Apple always do top quality stuff don’t they? Err, no. There are lots of reports of flickering screens, yellow tinges, etc. Apple released one firmware fix, but it did not appear to fix the problem for everyone. There is now talk of another fix coming. My best hope was this article where someone said running the fans faster fixed the problem for them. Basically seemed like a heat problem. This article was another approach – effectively putting it into screen saving mode for a bit to let things cool down (without turning off the whole computer). It also reported the iMac being very hot.
So I might let things cool down before buying one myself. Probably a good thing for those work deadlines too! 😉
I since found this Gizmodo page (http://gizmodo.com/tag/faultyimacsaga/) saying they are going to post an update every Wednesday until the issue is resolved. Worth a peek. It focuses more on the yellow tinge some people get, and suggests it could be something getting out of alignment if your delivery service is not gentle enough with your iMac in transit.
