Sure they do. My mother is still using my MacBook white 2008, which I upgraded from 1GB to 4GB RAM and replaced the battery. I also expect to get at least two more years from my MacBook Pro 2012 after upgrading my disk to a SSD and the RAM to 16GB.

Not everybody has the money to buy the next device, so upgrading is a great option to get a couple more years of work from a little old but otherwise solid laptop.
