I mean there aren't that many "small" laptop, just reading between the line of your needs.
Today most laptop starts at 13". I am not sure if that fit your definition of Small. But the new MacBook Air is pretty decently priced for an Apple product.
an iPad Pro 11" which I absolutely love, but is abysmal and no where near any good for coding on.
And currently eyeing that MacBook Air with a massive 2TB, 16GB, and i7 option for still less than the lowest end 16" MacBook Pro and just barely more than the stock 13" high end MacBook Pro.
