They both have 4GB DDR2 memory the toshiba has 500 GB and the Sony had 320 GB they are both the same size with the Intel Core 2 Duo processor the only difference is the toshiba has a bit more memory and they are both 2. 2 GHz i like the stlye of the vaio better so which is the better computer??? Toshiba or Sony?

I have an ancient laptop so thats still pretty excellent, but I'm so tired of it and would like another before returning to school this fall.
Is it in some way to tell how much to sell? excellent ways to sell it? continue? I would be grateful if you have any advice! thanks!
