I've always found that just developing in Windows, and using Safari for Windows has been sufficient.
However, Safari 6 has now been released, and I've got at least one user who has contacted me, saying he's experienced problems with one of my sites on his new ipad.
The trouble is that Safari for Windows only goes up to 5.1.7.
Do I have to go out and buy a new mac/ipad/iphone in order to test my code, or is there another way?
