One interesting thing I found is that the newer units add a "frequency" field. This is the Freq/offset/PL/etc of the other band. I think other manufacturers support this field as well. This along with a "tune" button makes it easy to QSY to make a voice contact. The D710 also does smart beaconing instead of every x minutes beaconing no matter what has changed. I think there's an aftermarket GPS that just clips on the back of the head unit that simplifies installation and cabling.
Anyone else have anything? I'm looking at upgrading my D-700 if I can find enough good reasons.
If you were asking TH-d7 vs TH-D72 it would be a no-brainer. The D72 is a huge improvement over the D7 (which is the main reason I'm thinking of updating the D700 too).
I have had a D72a for about 3 days now and I love it so far! I purchased a f6a first but it was deaf on the b side and useless for HF listening so I returned it for a D72a and am really enjoying it. I ordered a D710a yesterday, should be here on Monday, that will be exciting!
Nice. Make sure you get the latest firmware:

Yours shouldn't have that bug, but there was a release in November 2011. You might need that one.
