As the owner of the Padfone Club community, 6 year smartwatch user and gadget freak I'm waiting for Asus to finally make this...
I would immediately put up a Kickstarter if I had the right resources to make something like this happen, but I lack these resources :S
Current devices:
Asus Padfone (32GB), Android 4.1.1, Own custom ROM (T-Mobile NL)
Simvalley Smartwatch (512MB/4GB), Android 4.2.2, Stock ROM (Vodafone NL)
Expecting:
Omate TrueSmart (1GB/8GB Oct. Dev.), Android 4.2.2, Stock ROM
