Thank you for your perspective. I have no problem with setups, customizations, and the like, as I am a PC tech, and have done these kinds of things like modding/setting up original Xbox, PS2, etc.
Speaking of Xbox, I really like the idea of a frontend with video previews, and I am at the point now where I am wanting more than a frontend with just static images and text, which is why I like Hyperspin and Attract mode.
Frontends such as Hyperspin and Attract Mode dont exist on GCW Zero or Android (other than Shield Portable and the costly GPD Win), so I may just go with a Shield Portable. I had high hopes for the S192, but reviews of it seem unfavorable.
I may just get a GPD Win, or wait longer until the Vita homebrew seen really picks up.
