This is another case of misplaced expectations - essentially, folks like Chris set it up, in their minds, what expected 'secret' features are supposed to be (in this case, apparently and incredously, that Apple switch out their existing OS kernel with a Linux based one...??), and when such utopian features fail to materialize, folks like Chris cry 'foul', and take out their self-created frustration on Apple/Steve Jobs by writing blog entries claiming they were being lied to.
First of all, it's quite obvious that Chris hasn't even had a chance to get any closer to Leopard than the initial introduction, announcements, and the current Apple spec pages - because if he even had spent 10 minutes on a machine running Leopard over the past few weeks, he would know how silly his entire tirade reads, and he'd have come "....no to bury Leopard, but to praise it..."
Sadly, there's far too many jilted fanbois in the peanut galleries, who take their displeasure to blogs, when Apple doesn't exactly deliver what THEY want or expect.
Well, NEWSFLASH, Apple is not beholden to Chris' fantasies (I know, how preposterous), and holds a lot of other features in higher priority that Chris' priorities:
Personally, I consider performance improvements on the scale of 1x to 2x over regular Tiger systems, including on legacy PowerPC G4 based machines, to be more important - especially since that wasn't announced as a 'feature'.
Tighter and more feature complete integration with dot-mac, and other internet technologies will also stand out.
Lastly, when our iPhones will have new and improved features, that tie directly into new Leopard technologies, I have a feeling that there'll be a lot of happy campers around.
A HUGE number of improvements under the hood of Leopard will make all of these possible - and not preannouncing these quiet features could be considered 'close to the vest', and they will become apparent as more folks start putting Leopard to good use.... and Chris won't be waiting until 10.5.1 to rush out and buy it. I'm only wondering if he's got enough spine to revisit this silly article, and redact it.
Sorry, Children, Leopard's Top Secret Features Aren't Real
