I agree. I have a mid-2009 15" MBP to which I long ago maxed-out the RAM and replaced the HDD with an SSD, and it's still my daily driver.

About the only time I notice its age is when I do something involving very heavy disk i/o. While it is an SSD, it's still only SATA II. The vast majority of the time I don't even notice. It's been a great machine.
