A 208 sq-ft. mini-studio for $600/mo (+ the up-front purchase cost, whatever that is). That's $2.88/sq-ft.
By way of example, I found a 538 sq-ft. studio in downtown Austin for $1,387/mo. That's $2.58/sq-ft.
So, by area, the Kasita is more expensive. (This should not be surprising.) The argument then becomes one of absolute dollars: the difference between a 538 sq-ft. studio and a 208 sq-ft. Kasita being fairly moot, so hey, save $600+/mo.
And I laud this: I think there's a great market for micro-housing. (See also: all the "Tiny House" shows on HGTV.) I don't understand why I need to buy a "pod" and then convince developers to put a "rack" on their lots. Just build smaller apartments: the math should work out.
