And to follow up, it looks like the biggest difference is the Bionic will only have 512MB of RAM vs. 1GB for the Atrix.
I do seriously wonder sometimes why VZW always goes for the lowest specced device in a family. It seems like the same thing with the Fascinate; that seems to be the lowest-end Galaxy S device.
It seems like VZW is so concerned with profits that the thought of giving us an extra $10 worth of RAM is incomprehensible.
The bionic will also not support the netbook dock that that atrix will. So far it seems to me that the LG will be as good if not better than the moto, not sure where the thunderbolt fits in the mix. I'm due for an upgrade on the 17th of Feb.. I will not get the iphone, I'm hoping to get some hands on time with each of the 4g phones before I buy a new one.
