It was time to upgrade after nearly 10 years using this machine as an everyday workhorse. There is a small bug (fruit-fly size) in the lower left of the display - stuck between the LCD and glass which the Apple certified repair shop could not remove...I lived with it for the last 3-4yrs. This machine is a great solution for the casual user that wants some power when needed and doesn't need the latest macOS. Everything still works. I did experience a few random kernel panics when under heavy load (1x week?) - reasonable for a machine this old.
