A few questions about your use of ESRI Leaflet:
How fast is it compared to using ArcGIS JavaScript API Compact version (ie. download times)? Just wanted to get some ideas before jumping in. I have an app that I'll be converting to a new version, and performance is an issue. So I'm thinking about potentially using Leaflet. Our Spatial query stuff is quite complicated, so do Leaflets have many of the QueryTask concepts? Also, need some pretty advanced Legend stuff theoretically. Oh, and the main thing is that this app runs on all platforms and devices, so it needs to work well in all environments.
Also wondering how it does for building fairly robust applications?
Thanks.
