I agree that Chad want's to sell them the best but gawd...where does it end and the buying begin? I think their on revision 10 or so,hell this could go on forever. I would do revisions for a Company IF I had an iron clad purchase agreement good in the next 10-12 months. Sheeshhh,they could just use these units on 10 test fleets forever and never buy anything.
Wait...actually they HAVE been doing just that........
Iphone is on version 5 I think,just announced that support for #1 is over. Iphone 5 is light years ahead of 1 but what if Apple would have waited and waited and waited and never released anything for sale until now??
