I get that the size is big, even for me, I'd like a 5" at this point. But you know, if looking silly is the issue you can just go handsfree and use a Bluetooth handset with it. The advantage of the bigger screen is in other things, videos, reading, gaming etc.
While it does look ridiculous the main issue is that the size is just impracticable. Doesnt fit easily in pocket, is a pain to carry round, etc. I mean this thing weighs more than the 920 and that was already too heavy for a lot of people.
