Let the hive mind of Engadget get that for you.
"I'm looking for a pair of quality headphones that aren't seemingly made of glass. I'm an avid BMXer which causes me to frequently bash on any type of technology that joins me for my daily riding. I've been through the higher quality headsets in the Skullcandy line as these are supposed to be built for "abuse," which is laughable. I cant wear earbuds or canal buds, as my large ears seem to have a repelling property upon anything that sits in them. Wired or Bluetooth doesn't really matter, but I need something that can hold up to taking a few hits every now and again. I'm trying to keep 'em under $150. Thanks!"
I think it is the definition of Open Standard.
From a hardware manufactures point of view, it is. They can build one box that will work on both Motorola and Cisco based systems.
From a software development point of view, it is for the same reason. Write once, run on any system.
From a consumer point of view. Kind of. All you need to know is that your head-end is Tru2way compatible...you don't need to know if its a Cisco or Motorola head-end. From a software point of view, no probably not. Although, I do wonder, just how many manufactures actually want to code their own guide and other software or just use the standard MSO provided one. I know Tivo and Microsoft would obviously want to use their own guide (don't know about On-Demand and other apps) but I mean does Panasonic or Sony really want to be in the guide business?
