[wlug] MTP protocol - why needed?

Alas, more thread breaking in subject line. After a bit more reading on MTP it seems there is a rationale for its existence. That said, it appears that the protocol has not won universal acclaim.Some people are very scathing about it. In part my post was a bit overwrought as I had never heard of MTP, but then I have never used an Android phone until very recently. ~ Ian Y
