OK, let me rethink this...
Ars Technica's John Siracusa pens the most hardcore review of Tiger ever. This is like their USB key drive shootout, only on steroids and driving 100 mph the wrong way down I-80 with the top down. The pages on metadata totally revised my decision to skip upgrading. (OK, so maybe metadata isn't that sexy to most folks, but damn if this UTI stuff awesome.
Those of you who are intrested should read it. The rest should skip to page 18 which is a nice bit and has a Simpsons quote in it.
(Dashboard sexyness aside, I'm still sticking with Konfabulator. I like widgets that are always there. Plus, they are good people.)
