Fashion-obsessed! Yes, we live in LA, and here the question “who are you wearing” is more important than who is the producer of your film. Where once the young ingénue in Hollywood was the “It Girl,” now the “IT” is a wearable Information Technology device.

The recent announcement of the Apple Watch (which I predict will become popularly known as the iWatch despite Apple’s official name “Apple Watch”) brings new focus to wearables. And such devices will be redefining how we interact with all our electronic gizmos that connect us to our world.

We are becoming a world of portable computers, and we expect our communication devices to be at our fingertips. We want to hit the button to get answers: to call someone, order our dinner, buy a movie ticket, show a boarding pass, find out the weather, and solve a trivia question.

Personal wearables connect to our smart phones or computers and do all sorts of things - devices like the FitBit strap on our wrist to monitor our physical activities and conditions; we can even connect similar devices to our pets to monitor their activity too. We can even attach such gadgets to kids or the impaired so they can be found if lost.

We’ve had “wearables” for decades - remember when everyone was wearing a pager on their waist? And for how long have joggers been strapping their walkmans/iPods players/mp3/iPhones to their arms or waists? Wearables aren’t really new - they are just becoming more powerful, sometimes smaller and hopefully more easily wearable.

Once the typical electronic wearable was just an earphone speaker — over fifty years ago my grandfather regularly wore one from the AM transistor radio in his pocket to listen to the baseball games without bothering the rest of us. Now even the simplest earpiece is likely be a wireless Bluetooth device that includes voice controls for volume and functionality to answer and make calls, and that enables us to playback messages and even to dictate text messages from our smart phones.

And while I love the convenience of talking while driving wirelessly with my BlueTooth, I’m still waiting on a fashionable earpiece that looks like a good pair of earrings - I hate looking like a nerd with a techie thing hanging out of one ear. The fashionistas should have been in the Silicon Valley years ago!

The key to the success of our tradition of wearables is size; yes, size does matter. Frankly I am puzzled by the trend to ever-larger phones. The concept of the Phablet (the now popular mashup of a phone and a tablet) does offer better viewing, but only at a cost of convenience. I can’t easily slip an iPhone 6+ into my sports bra, in order to have it with me when I need it; with the latest devices, in order to stay connected, I need to be tethered to a purse or fashionable new clutch (I’m sure Coach and Kate Spade are working on a design for the iPhone 6+ clutch right now).

At times, I long for the convenience of my old Motorola flip phone, recently discovered in my “drawer of abandoned electronics.” Just slightly larger than a credit card, it had a luxuriously long battery life and never butt-dialed or cleavage-called anyone .

All of these wearables are going to impact our businesses too. Integrating personal and business technologies is an increasingly difficult challenge. We don’t want to swap devices, but we want to stay connected to home and office and share the conveniences of our portability in a telecommuting world. Businesses need to rise to this challenge.

Look at the wearables now in use: for example, swap meet vendors, bar wenches and Apple store workers carry cash registers around their neck or in their hands, and the new Apple Pay system will enable even faster and simple exchange of e-money.

Are you and your business ready for the wave of wearables? When customers enter your store wearing Google Glasses, will you be able to show them prices and merchandise? Office systems and retail operations are going to have to be “personalized” and integrated with wearables in order to achieve the efficiency that we are all expecting from these evolving forms of IT.

Your staff will have jewelry that glows when they get a call on their phones (indeed, there are nice bracelets and necklaces available today to do just that - but alas, no good earrings!). And while the “IWatch” that I may get for my birthday when it comes out next March will be a fun device - it is just the latest iteration of advanced-capability wearables.

The Apple Watch must still be tethered (albeit wirelessly) to the iPhone, and it is not yet capable of actually making calls - we are not quite at the level of the Dick Tracy watch. The problem is power - we don’t have batteries small enough to power all the things we expect from smart phones these days.

Once we can solve the powering problem, we’ll have the joy of truly fashionable wearables, in fact, when the powering issue is resolved, we’ll likely be getting implantables - that would enrich the medical profession, but put the fashion designers out of work. Be careful what you wish for…
