LG came out swinging with its line of Optimus products at Mobile World Congress this year, delivering the 4X HD, 3D Max, Vu and a trinity of L-series handsets. So how does one shop deliver six handsets to the public, you ask? Resources. A recent note to investors from Nomura Securities reveals that in 2011, the Life's Good gang assigned a larger portion of its R&D team to its smartphone division. The report claims that the company had 60 to 70 percent of its 8,000 person research outfit assigned to the Optimus-making arm at the end of last year. That's up from the 20 percent share of a 6,800 person staff it boasted just 365 days earlier. There's no doubt LG will be looking to steal the smartphone thunder of Samsung and HTC in 2012, but is this lineup of products enough? Only time (and sell-through figures) will tell.
