Mike Arrington believes he has tracked down what it was that made Robert Scoble cry the other day – a new piece of software dubbed ‘WorldWide Telescope’ that is set to launch at the TED Conference in 9 days.

This guess would seem to be likely on the money as Dan Farber even predicted this exact application being the cause of Scoble’s tears 3 days ago. He was able to pull together this guess based on some of the hints Scoble leaked out including that Curtis Wong and Jonathan Fay were the two behind the project.

Though not the Giant Onion or Doomsday Device I had been hoping for, this could be a pretty neat application: provided it does more than Google Sky already does. As an avid space-buff I loved when Google rolled out Sky layer for Google Earth, but was left wanting more – this application could very well expand on that, but there is one potential problem: word is that it will be Windows-only. Which means one thing: I won’t be using it.

Microsoft, if you really are setting out to create a piece of software that can “change the world” like Scoble thinks it can – please get off your damn high horse and release it on all the operating systems. Yes, I know it’s more work, but you are not helping your reputation any when you create something cool that not everyone can use.

If you think I am going to buy (or even use for that matter) Windows just to get one application – no matter how cool – you are sorely mistaken.
