Optimus Vu pictured next to its competitor Galaxy Note
The Optimus Vu has a 5 inch IPS-LCD screen whereas the Galaxy Note is 5.3 inch tall. But as the Vu has a display resolution of 1024 x 768 thus going in for 4:3 aspect ratios, the Vu is broader than the Note. The Note is 83mm broad where as the Vu is some 90mm broad so for using the Vu, you indeed need really big hands to operate it with a single hand.
