Anyone got 6.2 on their legacy RN yet?

I'm not sure it would be a winning case but you could make a case that supporting the new OS on old(er) hardware might actually increase sells. How? By increasing the resell value of the older devices more people would be willing to upgrade as the upgrade cost would be less. That's more related to the consumer market and as far as corporate having the ability to use the same OS on new acquisitions as their existing devices has to be considered an asset.

Since they were forced to move to an new OS how many corporations took a fresh look at the market versus simply purchasing the newer model. If they could upgrade their existing devices to the new OS it could sneak in via the back door and not have the "fear" factor of starting over with a new OS. Which again I'm sure caused them to take a fresh look at the market.

Much like corporations supporting multiple versions of Windows. In most cases they will do whatever they can to avoid it and if forced to upgrade you are opening up a can worms and you better hope you can once again come out ahead.
