There was a time not so long ago that I would cart along a laptop and a Palm device, in my case a Tungsten T3, wherever I went, whether on the road or even to a local school.  If I was making a presentation I would bring an LCD projector, which as we all know back in the day was about the size of a Pullman suitcase.  Needless to say, the equipment I lugged around was bulky, weighty, and it was all somewhat inconvenient.  But it was necessary.  As time went by, though, everything got smaller, faster, and more powerful (and often cheaper).  So I've been able to shed much of what I previously carried.  But there is a bigger question.  What does a person really need to maintain optimal productivity and connectivity when outside the office?  One of my goals in life is to travel light (another one is that I don't wait in lines if at all possible, but we'll save that for another day).  It never ceases to amaze me what I see people cramming on board airplanes in the guise of "personal carry-ons."  It just makes me more determined to stay connected, productive, and most of all, LEAN.  Anyway, all I carry these days are (1) a cell phone; and (2) a U3 4GB Cruzer.  No more laptops, no more LCDs, no more Palm devices.  The key that makes it all work is the Cruzer.  It is more than a flash drive on which you can store and transport files.  In fact, given online storage sites, even GMail as a good example, you hardly need thumb drives.  The beauty of Cruzer is that you can load your commonly used applications (for me, Firefox and OpenOffice are the main ones) and launch them directly from the Cruzer, a USB drive.  This allows much better security and utility when using a computer away from home or office.  And there is hardly a place anymore where you can't find an online computer to use—that's why I dropped the laptop.  Anywhere I present I call to make sure they have a decent projector setup but they all do these days ... no more Pullman-size LCD gear.  The Palm device is basically redundant with cell phone features and web-based storage and applications.  So, my advice is:  Travel light!
