Hi, I have a question regarding upgrading to Lion. I did some research on the Internet and it seems there are 2 ways to upgrade to Lion: 1) After buying Lion off App Store, run it and it'll do its magic and once it's done and restarted - presto, Lion ready for action. 2) After buying Lion off App Store, open the package and burn the InstallESD.dmg to a DVD/USB drive/etc. and reboot from there. So what are the differences between these two methods? And say I want to try out Lion before buying; if I download a pirated copy of Lion, the instructions say to install via method #2 (InstallESD.dmg way), but can I install it using method #1?
