This isn't like that at all....the phone can read bar codes, which is nice, it isn't some grand marketing initiative with tie-ins with Wired and all that. But I can see people replacing the old bulky symbol style handhelds for something like this.

For people who want to play at whatever the D&D world has for cons or even drop in game at random stores, etc, it's probably more of a problem since if they are all playing 4.0 you need to too.

Good point. For those that want to play in the competitions, they are probably out of luck, if they want to continue playing older versions. If they want to play at cons or gaming stores, I bet they can still find older version games to play in, though I'm sure they're rarer. And if they offer to DM a game, I'm sure they'll find players. There are plenty of people who won't switch, or will only switch grudgingly, who would be happy to play an older version.

And I still use Office 2000. :)

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.

John Scalzi wrote a hilarious exchange on his blog the sums up perfectly why this idea is made of fail:

Sony BMG spokesperson: We're pleased to announce we are the final major music corporation to release electronic tracks without that pesky DRM! All you have to do is leave your house, go to a selected retail outlet, buy a special card there, go back to your house, scratch off the back of the card to find a code, go to our special MusicPass Web site, enter said code, and download one the 37 titles we have available, from Celine Dion to the Backstreet Boys!

Kid #1: Or, in the time it takes me to jump through all those hoops, I could just download all 37 of those albums off of Pirate Bay.

Kid #2: Or, I could just scratch off the back at the store, record the pin number, go home and download the album through a Tor connection, so you can't trace my IP number.

Kid #1: Also, what's with this first slate of artists? Celine Dion? Backstreet Boys? Kenny Chesney? Barry Manilow? Are you high?

There's much more, but I didn't want to jack his entire post.

My response? That you are misleading people.

There are a huge number of sites in the interwiki linnk map:

Including for example, uhm, slashdot. And Citizendium. And Merriam-Webster.

And finally, I have nothing to do with the list. I've never edited it, never asked anyone to edit it, and I have no input into what goes on it.

I am sure you will apologize for spreading this information. Right?
