I have a 207 Macbook white 3,1 with a 2.2 ghz Core 2 Duo and 2 GB of ram. I currently have Snow Leopard 10.6.8 installed. On the Apple Store web site, Lion is a $20 upgrade. Is it worth it? I have read mixed reviews. I am also trying to decide if I should replace the 120 GB hard drive with a 120 SSD for around $60. I think it would offer a pretty good speed increase and I'm probably going to experience a hard drive failure with this 6 - 7 year old drive. I bought this for $100 and don't really have a good history other than the girl who sold it to me used it for college. I don't want to spend much on an old Mac but for some reason I think I need to.
