I bought the Macbook Pro 13 (2.4 with an upgrade to 256 SSD) at the beginning of feb.
I originally bought the Unibody Macbook 13 (2.4Ghz) model back in 2008 and was very very happy with it. A year later upgrading to the 15" Macbook pro, which for me turned out to be a mistake. Although I wanted a more powerful graphics card than the 9400M.. For me the 15" laptop was just too much to travel with and it turned out to be unreliable.
I was very aware 3 weeks ago that there would be an upgrade very shortly.
I bought this laptop without waiting as I had been very very happy with the Original Unibody 13.
For me this has been anything but a mistake. I will not be using a thunderbolt device anytime soon. I need the more powerful graphics card on the MBP 13 and going from a 10+hour battery life to 7hours does not appeal. Some days of light work my 2010 Macbook has given me a good 12 hours of word processing and surfing.
The windows Dell & Asus laptops that I had last year for work with Core i5 processors I found to run hotter than the duo core versions I had the year before and battery run times of 4 hours or less did not impress.
The updated Core i processors may have improved since last year, but since the recall on the sandy bridge processors, I felt I should wait awhile.
The duo core MBP 13 runs cool, has an amazing battery life, in a package that I was very happy with and all-round has proven to be reliable for Apple.
