I've been wanting to write up about the dashboard for awhile. It wasn't until I saw DrJay's post that I got the writing bug.
The UI has a little bit of a learning curve even for 360 users. This is all due to it's modular & multitasking design built around voice navigation. Those without Kinect will find it's not as easy to navigate, but so was the 360. If you are able to navigate the 360 without Kinect it's not much of a stretch on the XB1 either. So I don't think there's much need to address the usability for non-Kinect users. They have already added the necessary controller shortcuts for the stuff you couldn't do without Kinect(more later).
The one thing that makes it slightly confusing is that every function is considered an app. Take away all the apps & there's not much to the dashboard. "Settings" is an app, "Friends" is an app, "Messages" is an app, Then you have to understand there is basically only 3 permanent tiles on your Home screen: "Snap", "My Games & Apps" and "Disk Drive/Bluray". These are always available. You'll use the "My Games & Apps" the most. There you will not only find your installed games & apps there but also any games you own but have not downloaded plus your download queue. This is where pinning comes into play. If you're not using Kinect you'll want to pin your most used games & apps to keep from having to dig through the "My Games & Apps" section every time.
You also have 2 other permanent functions always available in the upper left part of your Home screen: Notifications & the currently logged in profiles(s). I can't comment on logging in more than one wireless controller, but I have a 2nd controller but it's a 3rd party wired one. And I can see where it's confusing. On the 360 it has support for 4 controllers with each having separate assignments based on the lighted quadrant of the Xbox Guide button & the Ring of Light on the console. Microsoft got rid of both of these on the XB1 & instead relied on the official wireless controller's infrared emitter to tell the console via Kinect which controller went with which person. Don't have Kinect or using a 3rd party controller? Then the system relies on you to tell the console & the game on which controller goes with which person. Another problem is there are no longer local profiles. You are either a Guest or signed in with a Microsoft Live account. It would be nice to be able to bring back local profiles, but I understand why they don't. Too bad since it's best to sign kids into the console using a local profile then upgrade them to a Live account when they are older. Oh well.
Back to the dashboard... The other thing you need to understand is the multitasking functionality. On your Home screen the largest tile is your current game or app that is minimized. It continues to run in the background. Gone is the Guide Menu & now your whole dashboard is always accessible. The 4 tiles below are the 4 most recent apps or games you ran. These are in standby mode & it's always changing. So you can't depend on these all the time(that's what the pins are for). They are there for easy task switching. That's why DrJay saw his Settings one minute & a minute later it disappeared. He must have launched more apps or games until it fell off the list.
One thing most people forget to use are the new "View" & "Menu" controller buttons. These were the "Back" & "Start" button respectively on the 360. With the "Menu" button or as most will call the "Hamburger" button, you always have access to the "Settings" at the bottom of the pop-up. No need to pin it. The "Menu" button is like the right mouse button click in Windows. It's context sensitive according to which tile is highlighted. In the dashboard it gives you the ability to "Manage" your game or app where you can delete it or your game save, "Pin" it, "Snap" it, "Go Full Screen", "View in Store" or "View Game Hub". When used in your Pins it gives you a way to organize them by "Moving to Front". Smartglass gives you an easier way to organize them by dragging & dropping them where you want. The "View" button is mainly reserved for use by the game or app. I have not seen it used in the dashboard yet.
The Xbox button is treated just like the Windows Start Menu button. Pushing it once gives you the Start Menu or Home screen. Holding it down for longer than a few secs works just like on the 360: powers on your console if not on, turns on your controller if not on or gives you the chance to turn off the console or controller if they are both on. The one thing I found confusing is that on the 360 the Xbox Guide button was used to activate certain things based on the pop-up toast notifications. If you had an achievement toast then a quick press of the 360 Guide button at the same time brought up the achievement info in the Guide. On the XB1 you have to press & hold the Xbox button for a few secs in order to get the same thing to show. A simple quick press just gives you the Home screen. It's been difficult to relearn that but I'm getting better at it. They also implemented a double-tap. Before the new Snap Center(somewhat replacement for the Guide menu on the 360) the double-tap switched focus between your main app & your snapped app. Now it's used to switch focus between apps, snap a different app, unsnap your app altogether, take a screenshot or "Record That"/record video. All these functions are mainly used for non-Kinect users. With Kinect you can use your voice to handle all of them.
So far I've pretty pleased with the dashboard. It's pretty powerful with it's multitasking capability. It's pretty cool being able to snap Skype & video chat while playing a game or watching a video. I have been using it to talk to friends before we start our game. The Party app has basically been relegated to a way invite each other into our game. We continue to use Skype in the background for voice chat. We switch to it in snap mode for video chat during our breaks. If you haven't got the double-tap of the Xbox button down(to use Snap Center) to switch between apps then it can somewhat daunting, but that's why I like using the voice commands more: "Xbox Snap Skype" "Xbox Switch". Also learn to use "Xbox Select" to get a list of voice commands you can currently use. Helps when you're not sure what voice commands to use.
Lastly, DrJay, they didn't give Forza 5 away to everybody. I assume the previous owner still has your console listed as his Home Console. He probably owned it & that's why you were able to download it for free. If he ever buys another XB1 & sets it as his Home Console you'll won't be able to play Forza 5 anymore.
