I pre-ordered the new "Tiger" version of Mac OS X today. I got a good deal on it (education pricing was $69 instead of $129). I was going to wait until I ordered a new iBook later this spring to get the latest version of OS X as well as iLife '05, but since I want to install Tiger on my iMac as well, I figured I'd do the honest thing and pay for an additional copy of the software. The previews of the update I've seen are impressive, especially Dashboard and Spotlight. I am also hoping the new Sync engine will make it easier to keep the settings and data on my various computers (two iMacs at home, an eMac in the office, and soon an iBook to boot) consistent.
