* Touchscreen should possibly have a configurable sensitivity level for both glove-wearing and droplet-resistance. Preferably it should still be a capacitive one, a resistive touchscreen would have too many trade-offs.
* A slightly bigger 256×256 pixel graphics display size is preferable for its binary alignment, affording some low-level simplicity – it has the property that its X and Y coördinates are each addressable with a single byte, with no out-of-bounds; its total number of pixels is 65536 (another power of 2), and each pixel is addressable with exactly 2 bytes, with perfect efficiency. The [http://Pelulamu.net/ibniz IBNIZ (Ideally Bare Numeric Impression giZmo) virtual machine], designed for fun minimalist demoscene graphics, has chosen 256×256 for its virtual display, and makes use of these simplicity advantages. If PineTime also chose 256×256 then it would be a target platform for unclipped IBNIZ demoscene programmes, which would be really fun to play around with on one's wrist!
