Nice design and operating system, but unreliable hardware,
This review is from: Apple 21.5-inch New iMac (Aluminium silver) - (Intel Core i5 Quad-core 2.7GHz Processor, 8GB RAM, 1TB HDD, NVIDIA GeForce GT 640M, OS X Mountain Lion) (Personal Computers)
Following ongoing problems with Windows 7, I ordered 6 iMACs for my team last year. Initially, we were all very pleased. The MAC OS is very user friendly and easy to use and the resolution and clarity of the display is fantastic. A particular advantage is that it is based on UNIX/Linux which made it very easy to integrate the new iMACs with our high-performance Linux cluster.
However, during the last nine months 3 of the 6 iMACs broke down due to hardware problems: on two the display blew up - with smoke coming out ventilation slits; on one the fan stopped working which led to overheating. The damage was covered by the warranty, but the iMACs had to be sent away to Apple Service and the repair took 2-4 week; during that time Apple did not provide any replacement. Fortunately, we had two laptops that our team could use as a replacement in the meantime, but this is certainly not the level of service I would have expected from Apple. So based on our (limited) experience, the hardware clearly does not appear to be very reliable.
