I'm considering the Charge, too, actually. I don't care if it's $300. My OG Droid is long in the tooth and having all sorts of problems. I don't think it will last much longer. I was banking on the Bionic being out in Q2, but now it's looking like late summer. I can't wait that long.
Really my only choices are the T-Bolt (terrible battery), LG Revolution (Don't really trust LG, plus it's the same processor as the T-Bolt so it's bound to have poor battery life) and the Charge. The Charge is looking like the best bet right now, seeing as the Hummingbird is superior and with their screen, the battery life should be quite a bit better than the unfortunate Thunderbolt.
I'm disappointed that Samsung takes so long to upgrade their handsets, but it's getting to the point where I just want 4G and can't wait much longer. I'm also a quite upset about the possibility that the new "Bionic" will be the Targa with that fugly camera lump. I wouldn't buy that no matter what the specs are.
I'd love to see something like the HTC Sensation, but I don't think anything like that is on the immediate horizon.
