With respect to the two 13-inch models, why do many advise against the higher model? The difference in their Geekbench scores is equivalent to the difference between the 2010 base 13" 2.4ghz C2D and my mom's 2009 iMac 3.06ghz C2D. Last year, had the 13-inch offered a 3.06ghz Core2Duo, I feel many would have shelled out the extra $300 without reservation. I have the i5 model. Fantastic and snappy. However, kinda regret not going for the faster model for some unjustifiable reason. I'm still within the exchange period. Please knock some sense in to me.
