I hope I'm not simply repeating something that's already settled but Enderle is an idiot. He rarely if ever has any idea re: what he's talking about. He's about as relevant as Dvorak except Dvorak occasionally get's lucky with a 10 year old prediction (the Intel move) even if it's totally coincidental.
Enderle is another one of those dumbasses who has been predicting Apple's demise for a Decade.
I can't go into detail about the Developer Builds because of NDA but they are no where near ready for release. Tiger looks like a very good, very solid update but it's not ready. They're making some big changes under the hood.. some of which weren't even available in time for WWDC. Some of the features publicly demo'ed at WWDC (and later web-cast to the public) were just recently included in Developer Builds.
Tiger is coming out in the Spring. Anyone who tells you differently isn't evaluating Tiger (or they're an idiot like Enderle). To Apple's credit.. they might be able to strike around the public release of Vista.. at least pretty close. Remember, Vista is shipping to corporate clients in December (so they can evaluate it for 6-9 months and not deploy it during that time) but it won't ship to regular customers till early 2007 on the current schedule.
sorry I can't give you more details but rules-is-rules.
ffakr.
Well since you're talking about Tiger how 'bout you spill the beans since we all already have our hands on a legit copy
