Great questions! I'd like to get my hands on ICS ASAP. While I know that it will come to the Rezound, then I've got some useless and/or redundant capacitive keys on the bottom of my screen (not that big of a deal, probably). I'm REALLY looking forward to a phone without any bloatware on it. The Nexus battery should be better, especially with the ICS enhancements, which is important to me. Superficially, I'm excited for a more versatile LED notifier. I'm also really looking forward to NFC and using that.
This is my first HTC device and I'm impressed with the widget selection, the ease of setting up email accounts, on 4G, the phone absolutely blazes. I have yet (only been a couple of days) had any kind of freeze, lag, or glitch switching between apps, pulling up sites, downloading apps/movies. I would have to agree with BMX that this is a top-notch phone... and I have yet to even sample the Beats part! Been too busy downloading all my old apps, playing with Sense and camera (which in my tests has been much better than the Razr, for sure). FWIW.
