My previous two laptops were the 2010 2.4 c2d 13" MBP and the 2010 1.86 c2d MBA 1.86 (4GB Ram, 128GB SSD). I am simply amazed at how fast my new 13" MBP is (core i5). Everything opens in a single bounce on the dock, now my MBA did this but I assumed that was an SSD thing. The new i5 feels easily as fast and snappy as the SSD equipped MBA with the exception of the boot time, though this too is way faster than my 2010 2.4 was. I guess everyone saying the Sandy Bridge won't feel any different unless doing heavy CPU intensive tasks were wrong.
