I think Global Entry is worthwhile. The program works as advertised, the cost is moderate (just compare the 100 Euro per year for the Dutch counterpart), and the enrollment is reasonably simple. I have good hope that renewals will be even easier, ideally without an extra enrollment center visit.
PS: Since that question was raised a couple of times, here is a quote from the news section of the
GOES login page regarding passport renewals/replacements:
You can now fill out your SENTRI, NEXUS, U.S. / Mexico FAST, U.S. / Canada FAST, and Global Entry applications through this GOES website.
Travelers with approved Trusted Traveler Program (TTP) membership can now update Passport and Permanent Resident Card information online.
