I wonder as far as price difference at production level goes, how much more would it have been to have included MHL in the design of the tablet. $1, $2, $3... lets be realistic, we all know that it would have cost Samsung a small, tiny fraction of a drop in the bucket, not even the whole drop, just a fraction of it, to have included MHL in the design.
For this, I, and I'm certain thousands of people who don't care for apple products, had to get apple. I ended up spending $400 on the least expensive apple tablet that had 128 gigs of memory so that I could establish the physical link. The cheaper apple was only 64 gig.
You see in my case, this was a purchase for an elderly person for whom being able to simply plug in a cable was the only option. And companies don't consider this kind of stuff....
Anyways.... good luck to all
