Guys I need advice regarding mac purchase. I presently own a 1.6 Ghz Powermac G5 with 3 GB RAM. I am willing to shell out 2000 US dollars, which to me is a huge amount since I am based in India. I could go for the iMac 27 inch with i5 Quad Core, or I could go for MacBook Pro 15 inch with the i5 processor. Both the machines would cost the same. I would prefer the iMac as it would beat the MacBook pro in terms of performance any day, plus the sceen size would be amazing. I am a little apprehensive to say the least about iMac 27 inch as there were plenty issue regarding the yellow tint of the screen, the ticking sound of hard drive and heat. Has Apple been able to successfully address the issues with the i5/i7 based 27" iMac. Thanks in advance.
