God Bless Ziplock Bags

After years of traveling back and forth between Europe and US, I learned a neat trick to organize the items in my carry on -- a wheel backpack full of thick double-zipper Ziplock 1 quart bags. How many of them? Ehm.....

• one for hygienic stuff (yes, a woman has certain sanitary needs)
• one for music (iPod, earphones, iPod charger, earphone splitter (if traveling in pair), iPod data cable)
• one for edibles (chewing gums, medicine, TUMS, vitamins, 4 tea bags (never expect random restaurants to carry a good tea)
• one for small electronics (European power adapter, camera, camera charger, camera USB cable, USB drive, phone, and phone charger)
• one for tooth brush, little box with ear plugs, hair pins, ear rings
  
• one for underwear & shirt for 1 day (experiencing lost luggage teaches you a lesson)
• one for sunglasses and European wallet (hopefully containing enough Euros to get me to a hotel)
  
• and finally our good old "TSA liquids bag"

All of this (plus a passport bag, laptop and few magazines... oh... and few empty plastic bags for stuff like gifts or receipts) fits into a regular wheel backpack which I use as a carry on. As a result, instead of searching through bunch of random junk in my backpack, all I need to answer is "Which bag is it in?".
