Why? In what way? Oh, right, #2 (or did you mean something else)

Two reasons not to expect MHL:

• it's not free (as in beer) so someone has to pay a license fee (see #11)
• the MHL spec talks about the connection charging the device; I'm not sure if that's optional or required, but I'm pretty sure you can't charge an N9 via its 3.5mm jack

Reminder: I'd be almost as pleased to see true HD output from an N9 as you; I'm not trashing the idea, just trying to keep expectations realistically low

Edit: removed potentially-confusing reference to HDMI. I wasn't referring to MHL as HDMI (see several previous posts where I refer to HDMI-via-MHL), but I see why it might have looked that way.
