I have a wireless laptop with about the same specs but 1256mb ram. Mint 6 Main Edition works just fine and the DVD reader shows DVD movies just fine. I love it.
The only issue I have is I cannot get 1024 x 768 resolution but I have a work around each time I use the laptop. Something to do with the video chip characteristics that I cannot solve.
Lindows, Linspire, Freespire, Ubuntu, Mint 15 Cinnamon, Mint 16 XFCE, Mint 17 Cinnamon 64 bit.
