I am finally going to install Snow Leopard today on my MBP. Currently I am running Leopard 10.5.8. My intention is to install a new larger hard disk at the same time, replacing the current 250GB drive I have, and then do a clean install of Snow Leopard onto the new 750GB Hard Disk. I am about to go out and buy the $29 version of Snow Leopard but will this work? I notice that there was a lot of confusion when Snow Leopard came out as to whether the $29 disk was the full version or just an upgrade disk. I have searched around but there seems to be a lot of conflicting advice. What's the story?
