TL;DR Should I include the "Android Virtual Device" component when setting up Android Studio? Any reason it's recommended yet unchecked by default?
Long version: I downloaded and installed Android Studio for Windows 64. I am now going through the initial setup wizard, and just chose the defaults so far (i.e. Install Type = standard, UI type = IntelliJ) but for SDK Components Setup I noticed the following: Android Virtual Device is unchecked by default, yet the description says it is Recommended. I plan to include all other (checked-by-default) components: Android SDK, Android SDK Platform, and Performance (Intel HAXM). So... should I include this component? / Any reason it's recommended yet unchecked by default? I haven't done Android development before, so if you can clarify what type of apps would use this component, that would help.
FYI here's the component description: "A preconfigured and optimized Android Virtual Device for app testing on the emulator. (Recommended)"

And is this component redundant / related to the Performance (Intel HAXM) component? Description: "Enables a hardware-assisted virtualization engine (hypervisor) to speed up Android app emulation on your development computer. (Recommended)"
