I was on show site for 3 weeks with a tablet and it worked really well for me. I put all of my shipping lists, inventories, graphics layouts and floor plans on it and I was able to quickly locate, open up and view any information I needed in an instant. I was also able to photograph and document things with ease. I was able to keep up with my expenses using a Concur app. I was able to book and check in for my flight using the American Airlines app. I was able to scan with an app all of the 32 trailers worth of exhibit properties manifests and bills of laidings. Vegas is the largest tradeshow and convention city in the world and my company now issues tablets to every floor ops manager and sales personnel on show site. They are just handy little devices and very easy to carry around. Very easy to loose if your not careful as well.

Of course, we all still need to have our laptops to do the heavy work, but the tablets certainly have a place in business and can pay for themselves in time savings and documentation when in the field. I see them being used in a similar manor in the music/ recording world. Great sketch pads for getting down quick ideas. I could see using it for songwriting. I was able to use the voice texting/ typing functions to write all of my notes on the iPad and I could see using it to write my songs by speaking to it as well to write lyrics.

I think Karyn's right about the Minority Report thing.  The arm waving is tiring.  What worries me more, though, it the use of spare eyeballs.  I already have enough stuff to carry.

Linear Phase
I'm not digging the glasses, wearables; like wallets and watches.  I feel like, "I'm not a borg."  I do not need glass.

We are really treading on having this tech surgically implanted, and I find that spooky.

You will be assimilated -- Resistence is futile!!   

Imagine a guy strutted up with his ba'ding'able wearables --- being the last one to step in a crowded elevator, he activates the large HUDisplay on his watch and whoaaa a naughty video instantly plays where it left off for 'everybody' to see.  Flatuence seems to take a backseat in this scenario.  

Actually, there's been complaints about inappropriate content being played in public places and on public transport.  So how does the law curb this behavior, should people not peekAboo and mind their own business, or should the sleezygeek be more discreet?
