Pros - folders/20" wheels
• handle a little better when loaded than 700c/26"
• easier to transport on a bus, train or car
• fully usable / good for commuting when not on tour
• wheels are stronger -- IF properly built
• Bike Friday: Fully customizable from the company, if you prefer specific parts; can build the bike much faster than most custom shops


Cons
• If you transport the bike in a hard case, you have to do something with the case / might limit you to loops
• price premium for the fold
• baggage and drivetrain is lower to the ground, can catch stuff / not as good for off-road
• people will constantly ask you about your bike
• potholes, bumps, curbs and cobblestones are worse with small wheels


IMO it's worth it if you fly constantly and/or were considering getting a custom frame and build anyway. Otherwise, it's just a question of preference.
