The only hedge against that is the ecosystem for phone & ipad development is still the macbooks And there are any number of ways around that. "Developer mode" iPads that run Xcode and a Unix shell and that start at $5000, or a web development environment that does builds on Apple's servers, or just release the internal Windows/Linux Xcode versions that they almost certainly have. Fortunately Macs are currently too profitable for them to kill, but that can change quickly.
