What's the definition of a smartphone?

I was asked this question the other day:

What’s the definition of a smartphone?

I didn’t immediately have an answer. I had the answer in my mind… I could feel the neutrons firing but not giving a distinct summary sentence.

Then I formulated this:

A smartphone is a handset that enables you to manage your work and social life via means other than just the medium of voice.

What do you think? The thinking behind my definition is that, irrespective of what platform or specific functions, the main element that differentiates a ‘smartphone’ from a ‘shit phone’* is the fact that you can DO stuff. Manage a diary that’s synced from your Google Apps. Use instant messaging to talk to your team in Singapore whilst on an extended conference call at the office. Browse a spreadsheet or powerpoint on your device whilst you’re waiting for the ‘check’ at the restaurant.

What do you think?

* By the way: Will people PLEASE stop ‘shit phones’ that only call or text as ‘feature phones’. They have next to NO features.
