Halo was conceptually ahead of it's time, apparently way ahead of it's time. Nano lubes sounds interesting, I don't think it had a chance, most use or go with what they know. The TF600 is still a go unless you heard something different, I check XTI's home page often and nothing has been updated, I doubt they share progress with DUFFY. It's anyone's guess how far along the TF is. I would like to know.
