You need a PC to turn in your assignment

I have been taken several courses using Coursera, the courses offered are wonderful, when getting to the assignment part, you could not use Ipad or Iphone which you used to watch the videos, you have to submit the assignment on a personal computer, not an Apple computer. This is very frastruing! Right in the middle of a course. Why can Coursera warn people who is about to start a course that a PC is required to submit the homework? At least you have a chance to decide if thats feasible before you jump in.
