i got a nokia N8 prototype this afternoon with me courtesy of Nokia Philippines.
sad thing to report, phonebook implementation is very similar to other latest e/n series phones.
active voice cancelation doesnt seem to be part of the feature set (again so stupid since video recording already works with noise reduction...hardware its very much capable)
there is sort of cut and paste under the phonebook but no cut and paste available anywhere else...would have been very usefull in the browser, writing msgs, etc. i remember when i bashed iphone when it first lauched without cut and paste, i can't believe nokia is doing it right here

STUPID!
the sim compartment is very hard to open. i had to open the memorycard compartment first (which isnt that easy to open as well) before i could open the sim compartment.frustrating! hope they iron it out of the retail version. ahmmm, the home button needs some getting used to...its small kasi for my liking.
everything else looks great. very fast indeed compared to any other symbian phone ive tested. used it all afternoon none stop, battery is holding very well, full bar parin. no surprise since walang wifi...yeah, its crazy i know. also didnt play any music much. videos capture and playback looks stunning. im truly impressed. loud speaker sound is full and clear no clipping. voice call is impressive even though it doesnt seem to have noise cancelation...its crystal clear. everyone i called says so. no noise or hissing at all. photos are very impressive (even in low light) so far it hasnt hang or any errors at all. photo/video editors is best in any phone ive tried. very smooth and fast with fantastic effects.
i use 3.5G under globe. though i notice when im not running any app that connects to the internet i get 3G on the display. when im surfing it switches to 3.5G.
