The Gnex doesn't really have enough to be a good successor to the N900.

I think the Note does, it has better radio signals, noise cancelling mics, better earpiece, better loudspeaker, better storage, better processor, better screen (larger and more pixels), it also has the S Pen to top it off.

I'm declaring the NOTE as the first true successor to the N900!

By the way I hate the cheap plastic feeling of the Samsung, but after comparing my NOTE side-by-side to a RAZR I have a different opinion.
It's very very light and makes the large size feel small.
The plastic is a shock absorber so it protects the insides.
The RAZR sounds good on paper but that Kevlon also feels cheap.
The N9 to me has a great "screen feeling" but the polycar feels like cheap plastic also.
The only thing that "feels premium" is the iPhone 4 and the HTC Legend which I think is the Mona Lisa.
