Well, actually, everything about the G2 is as good or better than the N5 EXCEPT having to wait/if ever/ to get the KitKat upgrade. I guess we'll see. There's always rooting, but I'd rather not resort to that yet. I don't regret getting the G2 in the least. I just hope LG doesn't leave us high and dry. HTC has already announce that they will have all the Ones on all carriers updated within 90 days (some as soon as 15) and Samsung and Motorola have already said they will have all of their "current" models updated quickly too. LG is the only "big player" not to clarify when/if they will update.
I wasn't trying to put the G2 down in terms of comparing it with the N5, in fact, I am fully aware that the G2 is probably one of the best spec devices on the market currently and will probably will remain that way for at least a few more months. I think the only downfall will be that LG and Verizon have to get together for updates. Though I will say that they have a pretty solid working relationship, even though many of Verizon's sales reps don't know enough about the phone to make a solid effort selling it.
I'm quite pleased with my purchase, and even though I have not rooted it yet, I am thinking about it. But as I have seen on these and other forums, one great thing, is that Google is trying to go around the manufacturers and carriers, by making updates to frameworks and apps instead of the operating system itself. This could mean a lot of great things for us as end users regarding the best performance possible.
I do agree that LG staying relatively silent is not great, but I do hope they stand behind this monster device as that's their only way to push Samsung. I think LG can be a fantastic Android company but they need to take the lead with readying updates faster as well as satisfying customers needs.
