I don't care about wimax, because it isn't available were I live. I think nokia should improve/perfect the usability of the internet tablet, making it a web tablet with a desktop/laptop quality browsing experience. -full speed flash support: n800 is too slow for some flash heavy sites (high bitrate video for example) -embedded video support (windows media, quicktime and real ) -full speed for Ajax heavy sites (google docs, reader etc. etc.) -should be perfectly stable: both Opera and the Mozilla browser aren't perfectly stable. (sometimes they crash: NOT acceptable ) -fully usable with your fingers: using software improvements and maybe a better touchscreen (multitouch??) -better outside usability : the screen of the N800 isn't viewable in bright sunlight, so a better screen that solves this would be welcome. -improvements in the text input methods: like a hardware keyboard, or working hand writing recognition, or other software input methods (trace writing, better error detection in words, a d-pad input method etc.) -bring back the Nokia 770 hard cover: it worked SO well, and protected the device perfectly. Adding other features aren't necessary in my opinion: -GPS navigation -slick looking UI with zoom effects (like the iphone) -better camera -stereo blue tooth headphone support they could be nice, but the MAIN feature of the tablets aren't fully mature yet and should be the top most priority.
