Will probably never purchase an iMac again! – After using a microsoft for so many years I was getting a bit bored and decided to get an iMac 27in all in one. Was it was great at the time as the screen is so big and with the wireless keyboard and mouse I thought it was a great concept. But after a few days I had to call Apple customer service as I was already having problems with it. Firstly they were not even going to help me as apparently if you go over 90 days they don't help you with any technical advice unless you pay them for a subscription. I only had the computer for a week but according to them it was when the store bought them. How wrong is that!! Next thing when they decided to help me they looked at my serial number and told me that there was a fault on my computer and that I would have to take a 27 INCH computer into a apple store ( In WA there is only 1 in the city) and get them to do an upgrade to the software. It has been a few months and since then my wireless internet has played up and intermittently comes on and off!! I have checked my internet connection, router, modem, wireless connection with every other device etc... and this is the only thing that does not work!! Very frustrating!! Apparently everyone is having problems with the iMac 27 inch computer. It has problems with the airport, IP address trying to connect to the internet wirelessly!! And apple can't even do a thing about it!! Some advice, Apple products are good, but don't get the macs!! Especially the 27inch!!! Stick with good ol Bill gates and get a mircrosoft!! All in one without the tower. Nice big screen. some added benefits Doesn't work wirelessly!! - confusing at times. Apple customer service are hopeless
