I always wanted Linux and Windows apps to feel native on Android, and I'm getting darn close. With Burrow, every Linux or Windows app installs as its own Android app, with its own icon and its own window. No root and no setup.
I have Linux and Windows applications working on Android. (2x speed because archaic lol)
Testing Windows apps for Android.
The other ways to do this never sat right with me. Termux + X11 gives you one Linux desktop in a single window that you set up yourself. Winlator is a separate emulator with its own desktop. I'd rather just use Android on my phone, especially on a foldable, and have these apps show up like any other app. So each one works with Recents, split screen, freeform windows and DeX.
Linux apps built for ARM run natively, with no emulation at all, so there's very little overhead. x86 and Windows apps still need emulation, and the Windows side runs on stock Wine on top of Box64, FEX and proot, which are the parts I patched. I've even had a test macOS app running on it. Next I want to try remote compute and pooling your own devices for storage and compute.
