Mid-2007 white MacBook here, 2GB RAM, SSD, on it's third or fourth battery. Running Lion. DVD drive died long ago, plastic on the front split after a couple of years but has been stable ever since. Been used every day of it's life by me and my kids (who were 3 and 1 YO when I bought it). Although now I am the only one who uses it. The main problem now is finding a browser that's supported and updateable - Chrome gave up ages ago, and FF48 is the last version to support Lion. Hates Flash though so I've long uninstalled that.
