Samsung's stuff has never really been that great IMO, I know Tegra 4 is a flop but I do think that they'll be really competitive once they integrate project Denver. You also need to include Intel as they will be competitive as well in early 2014 with "Merrifield" SoCs.
I don't think it would be a big problem, what I would do is leave it on it's own while LG works on integrating it, while giving it the cash it needs to compete with Samsung/NSN/Ericsson.
Right, which is why I still think they might make something like 1X, but have it only for voice/SMS. That's probably wishful thinking on my part though.
My hope is that LG tries to copy Samsung and buys Alcatel-Lucent (the network division, to be clear) so that Alcatel-Lucent could have the funding it needs while not taking a player out of the market.
