This is complete misinformation. The original Bionic (the Etna) was VZW's version of the Atrix. The new Targa is completely different. The only similiarity is that they are both built by Moto.
It's not complete misinformation and it's not completely different - it's slightly different. I didn't feel there was a need to repeat the fact that the Bionic is the Targa, not Etna.
How can you say they're completely different when you look at the specs, form factor, etc? There is a far greater number of similarities than differences. If the Etna was the Atrix for VZW, then the Targa sure isn't much of an upgrade from the Etna - which may be why they ditched Etna in the first place.
Lets see the differences...
- Camera - more megapixels - "meh" unless you're printing out massive photos for billboards and what not...

- Processor - omap vs. tegra - appears this will be a legitimately positive change
- Screen - larger screen, but same resolution and same pentile pixel mgmt... meh again
- 4G/LTE - true LTE radio vs. the Atrix on AT&T's pseudo-LTE... though this is more a carrier limitation issue
- 1080p vs 720p video capturing? I think that's different vs. the Atrix and maybe Etna... HD video recording as a whole on these phones is kind of gimmicky b/c it can't come anywhere near HD video recording on a real camera, and can't write to the SD card smooth enough to avoid choppiness - though dual core does improve on that somewhat, finally
- Form factor - yes the Bionic is bigger, and the Photon has the jagged edge, but as far as Moto phones go, they're in the same family easily - the iphone-esque shape
I really don't know what else... unless I'm missing something, that makes the Bionic nothing more than a souped up Atrix, which is all I was saying in the first place.
