Lessons learned

• Learning Ruby is straight forward

• Implementing SAP backend needs manual work

• Documentation of Rhomobile could be better and more up to date

• Good support via Google Group and @adamblum (CEO)

• jQuery Mobile slows apps down -> jqMobi is possible but much manual work needed
