A few months ago I replaced with my old 2006 2.16 Ghz MBP with a shiny new imac. Since then my MBP has been stored away collecting dust. I have not used it since the power supply died and the battery wont hold a charge anymore. I feel bad looking at it retired to en empty drawer, so I am getting a new power supply for it and start using it again. I would like to install OSX Lion on it but will it run ok?. It has snow leopard right now and it seems to work great with 2GB of ram.
