I haven't read through all 9 pages *blush* but my wish list includes.

* better battery life. If apple can squeeze 20 hours out of their iphone thing, then surely... surely!!
* oled display to help with battery
* motion sensor - for real kinetic scrolling. I think that motion sensing will become a very standard part of the UI of all small devices; shake and tilt to scroll through photos, contacts, text messages, web pages; avoid all the fiddly scrolling with a pad.
* what would be really nice is an option for a built in or attachable proper gamepad - so we can actually PLAY mame etc games on the thing
* of course would want it to play all video formats that I find on the web - really annoys me that I can't listen to blake's seven on scifi channel in bed on my n800
* come with a nice email client
* come with a podcatcher that just gets the podcasts when they're available and files them away and discards the oldest, nice thing like that (maybe I could write that)
* retain ability to have loads of storage; I love the n800 two sd cards thing, can just wait for the fatter and fatter SD cards to roll on out.
