Well, it was very informal and lots of people made comments and I'm 100% sure that they were listened to.

Hardware: There's almost no point feeding back on hardware. OTOH I had nothing to feedback as long as it works.

Software: Immense interest and communication around how to make it better... Verification to us that the SDK UI works. Also suggestions were made (by us) as to how the docs and guidelines could be developed. I personally shared thoughts on API for screen orientation - but that's on the -devel mailing list too.

Other things... suggesting the UI is different enough that videos and galleries would help... I think that was taken on-board.
Again though, when they release API docs ASAP then they aren't finished. We understand that and I'm happy that releasing early docs that aren't polished is much better than releasing perfect docs later.

We also discussed mechanisms about how we could self-support Nokia tablets after Nokia begins to end-of-life them and how this benefits the community and Nokia.

Nokia are making this easy - I have plenty of devices that simply get abandoned and freeze... my tablet won't be one of them.
