I'v found both phones for sale, both in great condition. The OMNIA is $50 cheaper than the G1 though.
I love all the features of the G1, not so much with the design though : \
I love the design of the OMNIA, and the features aren't bad i guess, plus a better camera and video recording.
So which...
The marines are a small tight knit community and they consider themselves elite.
If you've ever met a religious freak, they are crazy about it and would do anything for it. Thats kind of what the Marine corp wants, for their men to be the best at what they do and to do anything and everything...
