Why?
(sub-question: why not google maps?)
For me:
Same as why
(maps, like encyclopedia articles, are awesome information, lets have a free world-editable version!)
Mapping data is not free
Mistakes cannot be corrected

Nepal has its own set of

Off-line possibilities
(In contrast, included in the folder you gotis all of the VECTOR data for Kathmanduthat OSM has)
Apps! (both use and write...)
