Well, I'm rocking an N800 that's about 14 months old, with no plans to switch to an N810 primary (although the price is getting low enough I might pick up a used one if I see an exceptional deal, just to play with). I'll definitely be going for an RX-51 or Pandora shortly after they come out.
Well, it is a phone, rather than a tablet, and is missing the two big characteristics that made the NITs interesting to me: 800x480/225PPI screen, and Linux. For me, at least, the N810 was mixed vs. the N800, but the N97 is a definite step down. Depends what you want, of course, but with the RX-51 having data (and perhaps voice) connectivity, which to me is the N97's only real advantage, I'd wait till more details are out on it before jumping to the N97.
