I had noticed that images in my news feed on the Facebook app on my iPad 2 were displaying weirdly, but it hadn't occurred to me that it was likely a HiDPI problem.
("weirdly" = some images are blown up 2x bigger than you'd expect them to be with the full vertical dimension showing, but the right half of the image being cut off by the instant messenger window)
Now it makes sense, assuming that in the iPad app the News Feed is just HTML and that they probably didn't test the new HiDPI News Feed on older, non-retina iPads. I make that assumption with a healthy dose of doubt because I have no way of knowing how the Facebook app is designed or tested.
The takeaway for me is that there is now an even larger pool of devices/browsers/resolutions for which we need to test our designs. Choosing to go the HiDPI route, a noble decision in my opinion, comes with an even greater testing burden.
