Thoughtfix covers some really interesting ground in his interview with Ari Jaaksi of Nokia.
The N800 is discussed of course, some generic tablet/umpc questions and a lot of other stuff.
See his blog for details.
At the same time I’ve been working with John Tokash to try and determine that video playback performance. It looks like the current software is not optimised for the N800 hardware because the performance with a couple of sub 1mbps Xvid files wasn’t very good. Johns doing some more tests and promised to post results in his blog.
