It's an older version, yes, and it is not the most recent, but I love this. The 13-in screen is clear, and the battery life is 8 hours+. The software is more than adequate for my use. In fact, I have more apps that I use. Looking at the environmental costs of new products and the price of this refurbished laptop, this was a no-brainer.It is LIGHT. The lightest laptop I've had, and the sleek aluminum body stays cool after hours of use. I guess they fixed that heatsink/logic-board-overheating problem that was common in the first few generations.When I bought my first Mac 2GB laptop (wifi card or extra memory, optional) in San Jose, it weighed SIX pounds. Technology is wonderful. It gets lighter and cheaper.
