Thanks for the input all - it is definitely helpful.

Yeah that is the other reservation I have about the Galaxy Nexus. I do love the solid "metal" feel of my Droid.
I'm definitely on the fence regarding the hardware keyboard. I think I would prefer it but the other specs on the Droid 4 don't seem as impressive as the Samsung. Smaller screen size, lack of ICS, locked bootloader, Motoblur, etc. I don't know if I do enough texting (practically none) to justify needing the hardware keyboard. It would be useful for retro gaming though (like running DosBox).
But yeah, I should definitely try both of them out hands-on in a store before deciding. The Droid 4 is supposed to come out this Friday according to rumors I've read.
Thanks again for the input!
