The BDP-S570 can also be controlled using Sony's "BD remote" iPhone app. The idea is great, as there are quite a few times when we'd rather enter text using the iPhone's touch-keyboard instead of the standard remote via an onscreen keyboard. Unfortunately, the BD remote app's execution isn't quite right. The iPhone's screen doesn't replicate what's on your HDTV, so you're forced to look down at your iPhone to press a button, then look back at your HDTV to see the response. We're excited to see the next-generation implementation of this idea--especially if Sony can get the onscreen menus to show up on the phone--but in its current incarnation, we don't consider it a particularly worthwhile feature.
