I have probably only spent maybe an hour interacting with the X1 dashboard, but I definitely wouldn’t want to relive the X360 dashboard! Yes it may be easier to find things or what not as compared to the X1, but I always hate having to stop talking when dashboarding from whichever game I was playing because it has to load everything thus voice is cut or having to deal with “Xbox lag.” (I believe the dashboard is the cause for that because I don’t remember such thing existing when playing Halo: 3 or Call of Duty: 4.)
…I could be wrong when it comes to this topic because I’m not that great when it comes to the Xbox hardware/software, but I’m not a complete idiot when it comes to computers in general.
