I took my tomato-red daytripper on a recent trip.  It is everything I have been looking for in a carry-on bag or an overnight trip.  It is lightweight enough for me to stow in the overhead where it fits front-to back.  It has compartments galore so that cosmetics are separated from electronic devices and everything from clothing.  The attached, but detachable plastic bag for liquids was handy for going through airport security.  The bag holds enough for PJs and a change of clothes as well as tablets/laptops, cellphones, jewelry, etc..  The only thing I would add is a strap for balancing a smaller bag on top, as has been mentioned in other reviews.
