It's funny, everyone has their own experience and preference. I've never owned an LG phone but I've had HTC, Motorola, and Samsung and by far my worst experience for connectivity has been with Samsung. Between 3 Droid charges and a Galaxy Nexus on VZW I've seen pretty bad cellular connectivity compared to other devices. It generally seems to be in the firmware, which includes dropping data, getting stuck switching from 3G to LTE (resulting in no data), premature falling back to 3G when other phones don't, and generally just slower data, even though the received signal indicators seem to match other phones. I've never had any real issues with WiFi.
The Motorola phones (OG Droid, Droid X2, and Razr) seemed to be better, but the 2 HTC phones (Thunderbolt and Rezound) were solid. Well, the Thunderbolt wasn't at first of course, but we still have that phone and it outperforms the Galaxy Nexus in our experience.
I'm all for an HTC Nexus phone. I prefer LCD over Samsung's saturated screens. Their cellular performance seems solid, and as long as we blow away Sense, the phones are tolerable. Well, my husband likes Sense, but I'm a purist--can't stand any skins, hence me being Nexus only if I'm going with an Android device.
I'm happy without a microUSB as well but without it, I NEED the phone to have good connectivity because the worse the data connection, the more battery I burn when trying to stream my content that I'm not storing locally thanks to the lack of removable storage.
I'm more interested in the software as well, and it will be fun to see what Google has in store in the next updates to Android. I'm skipping this Nexus, as it doesn't tickle my fancy as much as my current toy. The Galaxy Nexus just has terrible battery life, so I had to move on from it. I'll wait it out on this Nexus, test drive the Android updates on my, at this point, WiFi only Galaxy Nexus, and hopefully come back to the Nexus Android train in 2013.
