Aaron takes a look at the LG Optimus F5 at Mobile World Congress in Barcelona.  Much like last year, LG's going big with their international device launches - this time, they're targeting first-time LTE users.  It's not the flagship Optimus G Pro, but the Optimus F5 still packs some strong specifications like a 1.2 GHz dual-core CPU, 4.3-inch qHD display (540x960 pixels), 5-megapixel camera, 2,150 mAh battery, and Android 4.1 with LG's UI.  Overall, it's very fluid and is a great option for those looking for a reasonably priced smartphone.  Beyond that, I think many will be drawn to the Optimus F5's comparatively small size.
