Hello, thank you for reading this. I would like to make iPad apps, and I want as cheap of a starting cost as possible. I have heard that I need a Mac with 10.5.7 in order to develop so my questions are: A) What is the oldest piece of hardware that can run OS X, especially 10.5.7? B) Can you remote to a mac using a Windows machine, and how many connections can it handle through remote? Thank you for your time.
