The FullLife offers several benefits over previous models, including:
Lightweight, durable design
Integrated exhalation vents for quiet operation
No forehead support for clear line of sight
Advanced cushion design for excellent fit
The design looks rather interesting:

The fact that it has no forehead support for clear line of sight, looks really cool. I looked at Respironics site, and they don't even have it listed yet. It's suppose to be released tomorrow.
I would love to try one of these out.
