They are apparently working on a patch to fix the online with friends problem.
I am planning to buy it soon so hopefully the update will be out by then.
The iOS feature i have no interest in, off tv play is way more important for me.

While there is nothing much coming in the next couple of months from August on we have Pikmin, Rayman, Watch Dogs, Batman Origins, AC4 all confirmed and possibly W101.
That's just announced games I am sure there will be some more announcements at E3 and the likes of COD is pretty much guaranteed. Second half of the year will be amazing.

I got the standard circle pad pro packed in with Resident Evil Revelations. It felt great, finished the game using it. Despite its ugliness, in terms of usability its perfect.
But I never touched it since because practically no games support it.
The other thing is I play my portables mostly at home, I wouldn't fancy having the attachment on and having to carry it around, too bulky.
