i think you're missing one important point : ramos alarm clock doesn't/can't solve the wake-up problem ( people just have to go to the bed early and have a purpose to wake up early ) and just another alarm clock screaming at 6 o'clock in the morning isn't "sexy".
If one would buy it, it would be because the nixie tube and remote control. It looks retro (=good ) but you can remote control it and it wakes you up by the "super hipster nerd" way ! I think you should remove LCD model or if you insist to keep it , give it a modern look ( aluminium case etc ).
