I received it as a present back in 2007. It has a 13" screen. 2GHz Intel Core 2 Duo. 1 GB 667 MHz DDR2 SDRAM. version 10.4.11. It had a new mother board put in it last summer. Everything works great. I also have a brand new extra battery still in the box. I'm clueless when it comes to anything technological. Thanks!
