I've had a NIT810 for several months now and I think it's an amazing device BUT -

Phones are going to get larger and threaten the utility of the NIT - especially when Skyfire becomes generally available.

AND

Netbooks are about the same price as a NIT and provide a better hardware spec (at the expense of some of the mobility/convenience of the NIT).

I am already thinking of getting a Netbook or a Nokia N96 (hopefully with Skyfire in the near future).

Cheers
