Excerpt: With the eTrex Legend, GARMIN has loaded a full basemap of North and South America into one small unit. The Legend is also designed to provide precise GPS positioning using correction data obtained from the Wide Area Augmentation System (WAAS).
Conclusion: One advantage over the eTrex Summit is the Legend's WAAS capability which means significantly improved accuracy. The calendar, mathematical calculator, and area calculator can actually be quite practical.
Pros: Small screen size, No barometric altimeter or electronic compass
Cons: Good TTFF, Good retaining of fix, Small size
