I'm running a Dell D630 on w/ nVidia GPU and 2 GB of RAM. I plan to upgrade to 4 GB soon, and hopefully an SSD.
Anyway. I'm wondering about the upgrade process for Lion from SL. Will the App store update work? What if I wanted to install it on my current System? I had to use Pirate EFI-X just to install SL on this system, though it runs on Chamellian. (Don't ask.. it was a long painful process, but works)
