Amazon has a pre-order page for Apple’s next revision of OS X, 10.4, or ‘Tiger.’ While there’s no release date, the $35 mail-in rebate shows a ‘postmark by’ date of May 31st, so I would expect it to arrive reasonably soon before then. There have been rumors that Tiger would be released on April 1st, but who knows.
If you’re a Mac user, there’s much to recommend Tiger, from the previews, including system-wide search indexing and upgraded versions of many of the bundled programs. Historically, I’ve found the OS X upgrades to be worth the $130 cost, but you wouldn’t hurt anything by waiting for a review (or the first patches).
