Hi, I am about to upgrade from my 5 year old black MacBook.. I waited for the MacBook Pro to be refreshed. The refresh impressed me that the '13 inch entry level Pro actually came with a i5. Impressive. But I was also wondering, is the MacBook Pro (2011) much faster than the 2010 '13 inch model? I don't want to spend a lot of money on something that is going to not be much faster. Thanks!!
