For all those disappointed in the iPhone display size, lack of new form factor...
Have a look at this concept video:iphone 5
Several (maybe 5-6) years ago, Japan's KDDI had a concept video titled:
Knock! Knock! Ubiquitous.
(Sorry I can't find a link)
It showed a transparent phone/PDA similar in size to the iPhone shown above.
Interestingly, AIR, the KDDI device had:
-- Siri-like voice interaction and control
-- Notifications, reminders, etc.
-- Online one-step shopping/payment like Amazon or iTunes
-- Hi-resolution cameras
-- Worked with a Kinect-like device for sensing/evaluation of body movement, like a golf swing
-- AirPlay-like capability to stream video/content to a large TV Display
-- NFC Bump Payment for purchases, boarding passes, etc.
-- iCloud-like concept of your content is anywhere, everywhere you are
-- Home camera monitoring
-- Remote control of home lighting, HVAC, etc.
Anyway, what seemed amazing, 5-6 years ago, is largely being delivered in today's mobile devices.
That concept iPhone 5 certainly looks good to me!
