Good to know. No landscape is no big for me because I always disabled rotation in the launcher.Next 3D ran just fine on my s4, so I have no doubts that the note will handle it. You lose some abilities with some 3D launchers. Next's 3D mode doesn't have landscape mode. But you can cram a lot onto one screen, overlap widgets, etc.
Their 2D mode in the same launcher is actually very nice as well.

Yeah, the more I mess with the Note 4, the more I like it. It may be my first dive into the Note line/phablet category if the Nexus 6 doesn't win me over.
If you have any questions about the Note 4 to help you decide, feel free to ask. I'll try to be unbiased
