So right now i am running snow leopard i love it. I am up in the air on lion i still have a few questions.1. If i download it from the app store what happens if it crashes or locks up do i just reboot leopard and will the app store remember what happened.2. will it give me more room on my hard drive.

To your first question: Yes. To your second: I don't know, doubtful.
