I bought a Sony Vaio (VGN-SZ650N) last year and I would kind of like to sell it. Here are some of the specs: Processor: Intel(R) Core(TM)2 Duo CPU T7500 @ 2.20 GHz Memory: 2GB Cache Memory: 4MB Windows Vista Business is pre-installed as is Microsoft Office 2007. More info here: http://www.docs.sony.com/release/spe...650NC_mksp.pdf Can anyone tell me how much it is worth?
