Sure. And I used to have a phone with a hateful connector that had a glow in the dark arrow on one side of the plastic housing. Treo maybe?
It worked. I was happy that it was there, and I thought it was clever-ish at the time. But it was more clever than smart. Smart is designing a connector that is easy to plug in, aligns itself, and can be done in either polarity.
That's what Apple did -- the obviously right thing that no one else had bothered to do.
Also, consider that micro-USB sucks for auto-insertion (docks, etc). It wasn't designed for it. Apple has never been shy abut breaking with common practice if they see a benefit for the product, and a few ruffled feathers won't stop them.
