Thanks for confirming my sanity. :) I guess it's off to Radar again...
<rdar://29115913> Default NSNumberFormatter created in IB fails to honour thousands (aka group) separator
<rdar://29115955> "Attributes inspector" for NSNumberFormatter should default to larger number for "sample input"
Quite a shame, as most developers probably just figure the default number formatter is the right thing to use, I'd wager that most apps out there are in fact not rendering numbers in proper localized format. :(

My app shows a lot of numbers, doing this in code would require creating so many new outlets. :( ex: Searching my xibs for "usesGroupingSeparator="NO"" gives 129 results.

In fact, a search & destroy of "usesGroupingSeparator="NO"" and "groupingSize="0"" in the xib seems to fix the problem for me. I'll probably go with that "solution".
