Hey guys I need to consolidate the remote situation… Which harmony is the most logical choice to play nice with the ATV and still work great with other devices? What advanced features are worth the extra coin and which can be kicked to the curb as just neat and shinny? I checked all the equipment that I am concerned about and all seem good…. Anyone want to comment on the ergonomics of the device? Does it feel good in your hand? I have read issues with timing on the remote for the ATV, and this is the device I am most concerned about it working with… Do the recommended “Pairing AppleTV and Harmony Remote” settings work correctly or do some still have problems with it? Any comments on any of these questions from those that have gone down this route? Right now I think the 550 has everything I require though I wouldn’t mind spending a few extra bucks if it is worth it to get a “better” model if it will facilitate upgrades and or is worth the cost for the feature. Any advice gratefully appreciated.
