In order to have the highest rate of reusable code across platforms, isn't it more practicable to use PhoneGap?
What about huge crossplatform projects, are there significant advantages of using Mono compaired to a framework like PhoneGap? We also tried Monocross and MvvmCross which are both great frameworks. Especially MvvmCross which is a very active and fast developing project. But both of them gave us some headaches while starting out because there's really some fiddling necessary to get it all up and running. When we tried PhoneGap we just downloaded and ran it which was a real ease at first.
Now we're debating about which one to use for small stuff like RSS-Readers and which would be more fitting for the big projects because we want to avoid of getting stuck with one of the solutions in the middle of development.
Of course we would also appreciate to hear about any other experience with those frameworks from other developers!
