They likely won't open up any iPad. It seems they will merge (replace) OSX with iOS. I saw this coming years ago. If I were a developer using OSX I would seriously ocnsider a switch to another unrestricted OS.
I love Apple hardware, and OSX is much nicer to use as a polyglot developer than Windows. A workmate of mine runs linux on his macbook pro, and it's really a pain. Apple has put so many thousands of hours into getting the trackpad working smoothly, while the linux drivers seem to have been hacked together during a weekend and are truly awful. Things like ignoring thumb input, scroll speed and tracking speed are terrible, just to mention a few.
