I'd hesitate to say I had any desktop apps more useful then omnifocus iPhone, which effects me more like a neural upgrade from a sci fi novel then a cell phone app. iPhone apps could be like primitive cyborg upgrades with a primitive MMI solution grafted onto the part where the human interacts with the machine part.
I hope people support apps with high prices and really cool stuff gets developed. the problem isn't price or value or anything like that, it's that no one has any interesting vision of what the future of this phone could hold.
