I have the phone now for 4 days - and I am simply amazed! Finally, again small but smart approaches innovation. This does not include the 5 megapixel camera (that `s in other Handy`s also), no, inspire me the little things, such as: - The Kartenslott: finally you fold down the flap on a mobile phone and pushes the battery and the memory card - flap, finished. - The memory card format: finally we are no longer just rely on Micro Memory Sticks, you also also Micro SD (even SDHC) Card use (and this far up to 6GB) - Finally is also the annoying (for me) Camera cover the predecessor missing - Finally a merge of K with the W series - since the K850i now tinkers also the Walkman Player 2 with Mega Bass Hear the sound of the excellent music - but also (very important to me in a cell phone) - You can hear and be heard by the other party - in truly high level - The reception performance - really quite outstanding (I had even the K810i in the same places 2 bar less and have now received at Places, because I could only dream about the K810i. Last but not least my mobile phone on top of that like visually very good and the processing has no equal. For me, currently the non plus ultra in the mobile market!
