Indeed a good discussion. I for one, is looking for the day I can do with out this 5kg knapsack I carry daily to work and where ever I travel. Content: a T40, charger, cables, Logitech cordless mouse (trackpoint and touch pad, both standard on the T40, can't really replace a good mouse), a heavy gauge Kensington security chain (oh yeah, you need it when you go out for lunch), thumbdrive (diskette drive? on a laptop these days?), USB charger for my cell phone, Palm travelling sync cable, and other small gadget you regret leaving at home.
If I can function as effective with this future PDA you mentioned say, in the next 3 years or so, perhaps it's a good idea to take snapshot of my knapsack and its content now. You know, the good old "Before" and "After" testament
