leopard

1. No, the only people who may get a discount are the people who buy a new mac between the announcement of the official release date and the release date.

2. You can upgrade to Leopard without any kind of reinstalling or file loss, although it is always advisable to make a backup beforehand, just in case.

 

1. No discount unless you bought a mac after they have officially released the next OS.
2. You can select the archive and install option and everything will be there inside the new OS when you boot up but always advisable to backup beforehand

 

$129

 

Price has been announced as $129 for a single computer license. No word on an educational discount yet, but Tiger was $69 with educational discount.

while it fine and dandy to upgrade the operating system, it can cause some problems. not just OS X, but any OS. I really do recommend a backup, find your install disks, and install on a reformatted drive.
