It's not a concern about maniacs hitting 18,000 theaters simultaneously, its about hitting one. Even if a single theater is attacked by one moron doing a copy cat attack, the people injured could sue the living bejesus out of Sony, and an the PR spin would be even worse than it is now. Personally, I think it should be leaked to the internet, so about a billion people can see what only a few million would have seen otherwise, and then release and uncut directors version on DVD 6 months from now after all this insanity has died down.

Hydrogen peroxide powered rocket packs fly for around 30 seconds, because they have a specific impulse of around 125, meaning that one pound of propellant can make 125 pound-seconds of thrust, meaning that it takes about two pounds of propellant for every second you are in the air. Mass ratios are low for anything strapped to a human, so the exponential nature of the rocket equation can be safely ignored.

A pretty hot (both literally and figuratively) bipropellant rocket could manage about twice the specific impulse, and you could carry somewhat heavier tanks, but two minutes of flight on a rocket pack is probably about the upper limit with conventional propellants.

However, an actual jet pack that used atmospheric oxygen could have an Isp ten times higher, allowing theoretical flights of fifteen minutes or so. Here, it really is a matter of technical development, since jet engines have thrust to weight ratios too low to make it practical. There is movement on this technical front, but it will still take a while.

That is weird. I talked to God just the other day and even He said Jack pisses him off. Then he went on about how Jesus roxors at Halo 2. You know, that God is a bit of a tool.

Let's take a look at this a bit further:

XBox came with networking capabilities out of the box. PS2, you paid 40.00 for the adapter. XBox could go online before the PS2, because XBConnect and Gamespy had software out to allow this to happen. Oh wait, how much did I pay for that? Nothing. The 'box also has a hard drive in it... out of the box. Wonder what Sony's gonna charge for that?

PS2 gaming might be free, but remember: you get what you pay for. With my XBox Live subscription, I have: One name across all games, which no one can take, voice communications in all games, a friends list for easy tracking, and the best part: downloadable content, right to my hard drive, and game patches as well, if needed.

I love these PS2 fanboys. I have all three consoles. Any game that comes out for all platforms, I'll pick up the XBox copy. Case in point: Check out Splinter Cell for the box, then try it on PS2. A lot of detail is lost on the PS2.

One other comment: How is Tribes 2 a Halo-killer? You must be kidding.
