Whether we like it or not, this is just a natural evolution into further mobility. Very few things can be as mobile as wrist watches and technology is going to change them again.
The iWatch concept is, I think, something more profound that just nano on a wrist strip.

You've got eight to 16GB of flash storage on your wrist -- you should never think about needing a USB stick ever again. All you need is the ability to partition some of that space to show up as a mass storage device -- it's not like iPod cables are hard to find anywhere you go.
If you're connected to an iPhone, that means you have access to the GPS -- that's instant Foursquare / Facebook Places check-ins from your watch right there. Or hey, just tap your watch while you're out taking pictures to store a log of geotagging data that you can sync up to your photos later on.
Why limit connectivity to the iPhone? We'd love to be able to see new IMs and emails from our PC on our watch, and the idea of a simple, wearable Apple TV remote control seems remarkably intriguing.
Trust us -- we can go on. Putting a multitouch display on your wrist opens up an entire world of limitless wearable computing possibilities, and we're sure we haven't even scratched the surface of what could be done here.

visually,
I think that removing limitations of nano's, well, nano screen creates various possibilities, including rolling information bar, for example, or wheel of icons. However, larger screen will also require larger battery (which the article mentions as a problem); wireless charging may be needed here. Also, the watch will definitely will of special type display, maybe color e-Ink?
Now, being watch and being miniscule, it certainly will be bluetooth or NFC enabled to pair with iPhone (5S or 6).
Doesn't need a very good camera or speaker, no one will listen to music on it, mainly calls or voice messages.
Can monitor your health data every second, blood pressure, pulse, temperature.
Can inform you and your family about your location.
Can be used as an SOS activator in need.
Can be used for locating kids after school (if they wear iWatches)
Can be used as an early warning system for natural disasters if it has location abilities (wifi GPS or combined with iPhones' GPS).
Can be used for monitoring information on stocks, news, whatever.
Can be used for some specific games for that prolonged wristband type displays (sentinel?)
TV remote, gesture monitoring?
and so on.
