On the fence about preordering and waiting for a price drop (I did vote for waiting for a price drop). Given the current prices of flagship phones the V30 is competitively priced. If the preorder deals are good enough I might preorder.
I like it that the V30 is lighter, has a much improved screen and the new audio/video features are interesting. However, my V20 is working fine.
Since I'm on Tmo, the 600mhz support is also compelling, though I don't think I will see 600mhz in my area (Chicago) for awhile.
