We're not sure what focus group studies are providing fuel for this race toward 5-inch smartphones, but at least now we can compare two of the most fashionable candidates side by side: LG's Optimus Vu and Samsung's Galaxy Note. The first image of the two jumbo Android smartphones has emerged from Korea, showing LG's squatter 5-inch device is a little wider and bulkier than Samsung's more elongated 5.3-inch tabletphone. This is partly down to the unconventional 4:3 aspect ratio of the Optimus Vu display, but it's also difficult not to notice the generous bezel that LG has equipped its pseudo-smartphone with. A screenshot of the user interface accompanying the above photo shows a lot of pen input options, suggesting it'll match the Galaxy Note in offering a stylus for the mobile professional. Or the idle doodler.
