I agree with that sentiment - except that I bought 12, too. To me, if 13 is what 12 should have been, then it's like I'm paying $120 (or $95 after discounts) for a
potentially decent 13. That value doesn't cut it for me.
After a couple patches (assuming they don't create even more problems) and price drops, it may be worth it to pick up 13. We'll see.
