Ahh... iPhone how you have come to be an extension of my very being.
I don't mean to look like a pompous arse with my smart phone and certainly wont go to the extremes of checking work email out of work hours (not yet anyway... not paid enough!). However you have made my work life balance harmonious!
No longer do I panic about what is happening at work today that I may have forgetten, there it is in my calendar, synched with the server. With pretty much an app for everything all aspects of my life seem to merge into one homogenous blob that slips fluidly from work, to play, to rest.
