forgot to mention this:

the 770 may be 1.5 yrs old, but I wasn't, as many others weren't, able to get my hands on one until barely a year ago, and not for lack of trying, either.

And for those who said those who bought the 770 right before the advent of the 800 should have done their research first. Please. We all knew somehting was coming, even with the FCC filings, but the exact what and when were kept in the dark from us mortals.
