Thanks, Rob. I'm curious to hear your impressions. It sounds like these things are almost all terrible. I think it says a lot that since Google announced Miracast support as a part of 4.2, I haven't heard a single thing about it. Not from Google, not from the tech podcasts I listen to, not anywhere. Strange...

For my trip, I ended up just buying this thing, which unlike the Miracast devices gets good reviews. It's not as convenient because you have to plug it in, but that's okay. It'll work with my Nexus 4 and with the Nexus 7 2nd gen that I'm hoping to pick up before we leave. I'm not sure what's different about this from the MHL adapters, but it looks good.
