I too am using a 2009 MBP. Installed a SSD ages ago and replaced the battery about a year ago. Running Mavericks. Good for browsing, emails, etc. Use a beefed up Ubuntu desktop system for serious development work. Anytime I walk by an Apple Store, I test out the latest systems. The keyboards don't feel right for me. And the touch-bar hold very little appeal for me. When this MBP bites the dust, I'll probably get a PixelBook.
