ideaspotting, a great book about setting up your daily life in a way that encourages creative thoughts and ideas. There's a section on travel--and the importance of it for creativity--and a page that speaks to the need to let go of the gadgets that keep us too tethered to home and home jobs.
"We can't spot new ideas while dealing with old ones. Yet too often we head off on vacations only to let phones and e-mails bring us right back."
You can't experience the full effect of the new place if you are still tethered to the old one. Nothing is more discouraging than seeing a crackberry addict giving his thumbs a workout while a whole new world is swirling around him. Go away for real. Use gadgets that enhance your travel experience. Don't be ruled by gadgets that just allow you to carry home with you wherever you are.
