I just got rid of my Eris for the Optimus so not really an apples-to-apples but a little close.

Call quality seems as good as with my Eris.
Texts seems to come through just fine (the few I get - I mainly use Google Voice).
Google Navigator works like a charm as expected
Pandora works just fine
Facebook - again, fine. But you will have to manually "join" your contacts that sync with the app because it doesn't have the htc facebook sync, it uses the facebook app's sync
no flashlight or LED
Google Voice works fine for me when you deselect direct access to voicemail under the settings for your mobile phone in Google Voice. that causes it to go to your google voicemail as opposed to the phone's voicemail.

I used to use my old Eris on PagePlus, so while still a good deal, I only had 50MB data/mo (w/ 1200min/1200txts) and this while having unlimited data thing is just awesome for me as I don't talk much on the phone, really.

 

The Optimus V only has 170Mb internal storage, whereas the DINC has something like 6Gb, of which I think that 700Mb or so is available. This will affect the number of applications that you can have installed at any single time.

 

But that is what sd cards are for up to 32GB

 

Just remember there is no roaming with virgin. So, you will not have service away from metro areas or the interstates for the most part. I live in SC towards the mountains so I have a big hole of no coverage. What I do is I have a cheap tracfone running on Verizon towers in reserve for mountain trips or trips where I have no VM service. Still comes out cheaper in the long run than staying with Verizon.

 

@nightbreed813 - I agree, but there are some apps that you can't move (Facebook is a good example), or they leave stubs on the internal storage.

Unfortunately, it gets eaten up pretty fast on the OptimusV compared to the DINC.

 

Moving music to the Micro SD Card shouldn't be an issue. And yes, the power input is Micro USB.
