As for memory - it's one (1) gig of good RAM, no swappolube needed on these babies.

As for GPU - yes, SGX530, but the question you should be asking is 'what clock'. Night and day compared to N900 even though 'in theory' it's the same thing (yaright).

As for keyboard. I'm a qwerty dude, and know this is a polarizing issue. The virtual keyboard is good, so unless I'm ssh-ing or ircing, I actually use the VKB even on the N950. So yeah, it's good.

As for landscape mode. Sounds good, but apart from video/mail/surf it doesn't really make sense for the N9s form factor. I would say it's around the level of iOS' landscape support. The N950 is obviously a bit of a different case because of qwerty.
