Further to the subject, having just come back from another interstate trip, I listed what my phone does for me and I nearly freaked out.
It's my 1) phone, 2) GPS, 3) Music centre, 4) Camera, both still & video, 5) email, 6) fax machine, 7) web browser,

alarm clock, 9) eBook reader, 10) watch, 11) contractor locator, 12) international clock - so I don't inadvertently wake someone up in the middle of the night, overseas 13) TV guide - HA, whenever that is, 14) weather report - including local realtime weather radar - ideal for outdoor broadcasts. 15) Contact & address book. 16) Phone book - both local & international. 17) Diary, 18) SMS, 19) Note taker. 20) Skype interface, 21) Calculator, 22) Post code finder, 23) Bank interface, 24) Units converter, 25) radio, 26) Spell checker, 27) Distance finder, 28) Wikipedia & dictionary, 29) Shopping list reminder, 30) Bar code reader, 31) Language translator, 32) Airline booking interface, 33) airline boarding pass - they text them to you now, 34) Restraurant finder, 35) Facebook interface, 36) Twitter interface, 37) and during those idle moments waiting in airport lounges, I have 3 games I can relax with.
And yes all that horrible Social media stuff is essential work related stuff. Needless to say, if I lose it, I'm lost. Isn't that dreadful. I know a lot of you are going to throw up over this.
Be safe, well and happy.
Lotsa huggs
