I presented this week at the iPhone Developer Summit iPhone Developer Summit an alternative option of app development for the iPhone or any mobile device. The basic premise is to use the Tools or Development platforms you allready know to modify or build applications that can optimized for viewing on the iPhone yet actually run on XenApp servers within the datacenter.
The concept was very well received by non-developer IT Pro's and developers that are experts in other platforms, now trying to get their head around Objective C and other iPhone specific considerations. For the existing iPhone Developers the concept was foriegn and they remained skeptical. Thats OK, there is lots of room for more native iPhone apps and reason's to go mobile. As soon as users get the taste of leaving their laptop home there will allways be all those other app's or docs they will want access to. For help on getting started go to our Page on CDN
