I am upgrading to Snow Leopard soon and have been reading threads around here, saying that it might be better for a erase and install (less bugs and faster). Here are a few questions: 1. Is Erase and Install really better? Its just that I don't want to go through everything again. 2. What's the deal with iLife? The Application DVD includes iLife, right? 3. How can I do an Erase and Install? Erase the drive in Disk Utility and install Snow Leopard? Doesn't it look for Leopard first? Which drive to I select: Macintosh HD or the physical hard drive? Thanks.
