| XNA | FNADroid | FNA | |
|---|---|---|---|
| ID | Ascending HW / system identifier (1) | Ascending, next free (Android-esque) | Ascending, n-th touch |
| Desktop support | None (Win7 only, stub) | Disabled by default; FNA_TOUCH_FORCE_ENABLE | Enabled |
| Multi-touch-capable | Yes | Yes | Broken |
| MT Drag gestures | First touch only | Additional touches inherit first touch gesture | ---- |
| MaximumTouchCount | Always 4, ignoring additional touches | Always 8, handling more | Always 8 |
(1): Single-touch is timestamp-alike; Additional touches on multitouch behave like FNA. Keep Android-esque as extension? (pro: cheap finger tracking; con: less "accurate")

The "Touch" namespace has been removed by this commit from upstream FNA. The previous code was based on MonoGame's implementation of the "Touch" namespace while FNADroid further builds upon it.
