If you've ever struggled to jam your clunky carry-on bag into an overhead compartment then you might appreciate Truco. It's a three-piece carry-on bag which can be separated or reshaped as necessary.
The 20-inch bag consists of a small carry-on, a laptop bag, and a personal valuables bag. It uses something called a "click-on system" to keep the different modules securely joined, but easily separated. It can be ordered now for $US200. [Balanzza]
