IBM Worklight looks promising for mobile development! Reducing development time and costs sounds good to me. Offering the ability to develop different app types is a major plus - web, hybrid, or native.
"IBM Worklight enables the creation of rich, cross-platform apps without the use of code translation, proprietary interpreters or unpopular scripting languages, while reducing the time to market, cost and complexity of development while enabling a better user experiences across a variety of mobile devices."
