I am intrigued by a Note sized device. That would be incredible for watching videos, but I think it is too big for me. My hands are on the smaller size, so I think the Galaxy S3 is about the practical limit for me.
I cut mockups of my titan and note before purchase. The note did not fit my pocket. The top edge of the phone was above the bottom opening of the pocket if that makes sense. So it stuck above the bottom of the pocket opening. This would have allowed a slick plastic device to slide out of my pocket. The titan was just below the opening so when seated the pocket corner caught the top of the phone keeping it in my pocket a little better. I will not be going with a device that is any larger than my Titan. Bigger screen sure, not bigger device though. I am 5'8" with a 32" waist and 30" inseam to give you an idea of my jean size.
I think Nokia will make it. They keep making hints at something big. Either that or pureview either way itd be interesting to see wp8 on that big of a screen. I'd love typing and watching full HD movies on that thing that's for sure.
I am all for a Note II sized WP8 device the note II has a slightly narrower and taller form with full 16:9 screen and a more useful stylus according to review on pocketnow today.
