There's the official version of the Leopard sneak peek on Apple's (Nasdaq: AAPL) Web site, and there's the unofficial version, already leaking out all over the Internet.

At least two BitTorrent file-sharing sites were showing a 4.27 GB torrent for "Apple Mac OS X Leopard v10.5 WWDC Preview Beta," as of Monday evening. One can assume that Apple's legal team, which went after bloggers who published inside details about the company last year, will be all over this.
