I don't think I could be without mine now... but I do use it mainly for text messaging, rather than actual phone calls, to the extent that I have 300+ free minutes to use every month.

And here's a phone shanty for you from me.....

Well I thought I heard a mobile phone
And you think so, and you know so
Well it rang in the middle of me journey home
A long time it rang

Well I thought I heard the owner say
And you think so, and you know so
I'm on the train love, I'm on my way
A long time it rang

Well I said 'To me that phone you'll pass
And you think so, and you know so
And I stuffed it where the sun don't shine
A long time it rang!

Well if you've got a mobile too
And you think so, and you know so,
Better turn it off now or it'll happen to you
A long time it rang!
