You should upgrade to the thunderbolt and let your wife have the incredible! jk. sort of.
Fascinate is pretty good once it's rooted, and the droid x has a loyal following. The incredible 2 should be out i think in early q2 so that isn't too far off, if you can wait it out a while.
And there are the other 4g phones that are coming out in the next few months, the samsung charge, lg revolution, and droid bionic.
I got the thunderbolt a few weeks ago and it's working well, 4g speeds are crazy, but ultimately it's like a droid incredible in a bigger, heavier body. That said, however, i really like it.
Another option is to buy a slightly used incredible on ebay or something.
