As an econ. major I am surprised no one has given any reference to cost and benefit analysis.
From a pure minimize cost point of few, there is absolutely no reason NOT to enforce wearing helmets. Here is one of the studies that I analyzed in the past:
 
http://www.ncbi.nlm.nih.gov/pmc/articles/PMC1614783/

Legislation requiring bicyclists to wear helmets in Israel will, over a helmet's 5-year duration (assuming 85% compliancy, 83.2% helmet efficiency for morbidity, and 70% helmet efficiency for mortality), save approximately 57 lives and result in approximately 2544 fewer hospitalizations; 13,355 and 26,634 fewer emergency room and ambulatory visits, respectively; and 832 and 115 fewer short-term and long-term rehabilitation cases, respectively. Total benefits ($60.7 million) from reductions in health service use ($44.2 million), work absences ($7.5 million), and mortality ($8.9 million) would exceed program costs ($20.1 million), resulting in a benefit-cost ratio of 3.01:1.

 
Barring signicificant difference between Israel and US people (no, getting hit by RPGs don't count), the benefit grossly offset the cost.

So what we have here is Itanium- look good on paper but impossible to be fully utilized.

That constitutes a failure if you ask me.
 
Actually I hold the exact opposite view. The hardware isn't ready, and by not ready I mean the performance isn't as high as expected due to design issues.
If I am correct Intel doesn't want a repeat of the 1st gen Itanium where on release the brand name is blemished by the less than expected performance. This perception that IA64 is slow continues to haunt Intel up to this day. So by delaying Larrabee, Intel will have time to improve the cpu to the point where on release it will be a killer product (ie. hyped).
 
It's not as if Intel needs Larrabee in the near future anyway- AMD doesn't have anything significant in the near future as well; even if they do, with Intel's brute engineering capability, they will just pull a Core2 again.
 
Another possibility is that no game company is able to support Larrabee's architecture. Rather than releasing a product that 1. nothing old can run efficiently on 2. nothing new is designed for, Intel is delaying the release until more developers hop on the gravy train. When that happen, Intel can release the chip and immediately, consumers will be awe by the chip's performance in the newest games.

That's what happened to me.

I used to play MMO frequently. While I would not play 12 hours straight, I played way more than what a healthy human being should devote his time into.

One day, one of my friend got unlimited (legitimate) GM access to one of the most popular MMO game in the world at that time, and I started 'padding' my characters with all sorts of extreme enhancements (+99, set items etc.) It was very fun to begin with.

After 3 days, my addiction was gone- It's like an epiphany- I suddenly jock awake and realized that, all the efforts you threw into the game will only amounts to a few bits in the game bits database.

I never got addicted to another MMO after that.

PS. But then, of course, the same concept also applies to the number on my bank account...but that's another story
