31. 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
