I am the happy owner of a Macbook Core2Duo from the end of 2006. It's a great tool and I enjoy it really much, but it start to have some issues after 4,5 years of intensive use and I also saw that I use computer 90% of the time at home, so I'm thinking about getting something more powerful, with better ergonomics and with a wide screen to avoid to kill my eyes. I will use the iMac for browsing Internet, work with Logic Pro and play Football Manager, my doubts are: - 21,5" or 27"? The 21,5" seems to be enough but here I read of many people who regretted the purchase afterwards. I am looking for a new job and this also is important to consider, since maybe I'll need to relocate by plane (I'm from Italy but at the moment looking for jobs in Japan and North America) and I wouldn't know how to carry a 27" (indeed the 21,5" would be problematic too). - 2,5 - 2,7 - 3,1 GHz? i5 or i7? For Internet is the same, which improvements could I expect with Logic? And with Football Manager? - which graphic card? which is the difference in performance of these cards? For the RAM I don't care, anyway I will buy (if I need it) aftermarket, so at the moment is not an issue.
