Hopefully this D2 will get me through July 2011, and I'll have some LTE options then.
If you are going to upgrade right now I would definitely suggest an Incredible. The X is meh, the screen is nice but that's about it, and I personally think the bootloader will never be cracked so that phone living up to it's potential is unlikely. I had one for 2 weeks and swapped it out for an Incredible and couldn't be happier. There are some really good ROMS out there for it should you decide to root. I personally am not upgrading again until some LTE devices are released. Just my $.02...
I was thinking of going with the Dinc, since Verizon has the BoGo free offer. Get a Dinc, and maybe a X or a D2 and sell for a few Hundred to put down on a newer phone down the road.

With the buy one get one free, don't two people have to sign a two year contract or be part of a family plant. Thus, there will be an fee if one phone is sold?
As for a two year contract? Why. A one year contract is only 70 bucks more and you can then replace a phone every year vs. every two years.
