What one bit of technology could you not do without?

In the course of a day, the most useful piece of technology, from my perspective, is the Smartphone. Not a mobile phone, a Smartphone. The Smartphone lets one connect with the world through 3G (or 4G if one is lucky enough to live in the USA), enables one access to his/her photo collection, list of contacts, twitter stream, Facebook updates and posts, photo and video opportunities, the chance to learn through TED.com or ed.TED.com or even Youtube, listen to one's playlist, the chance to keep down one's email inbox, txt the family and even, make a phone call to anyone in the world (free through Skype..thank you very much).

Without the Smartphone (pre 2010), one relied on a camera for photos, a chunkier digital video camcorder for videos, an iPad for apps and a netbooks/laptop for access to the internet, a newspaper to read the daily news and a landline to take phone calls. Now, all is possible with a Smartphone which, as it names implies, is smart and getting smarter. Geotagging, image stabilsation, better graphics... the list could go on.

Think what you will but without a Smartphone could you rely on yourself to function in daily life...just think how you feel when you leave your Smartphone at home....oh, that's right...peace!

What piece of technology could you not live a day without? Hmmmm.....
