Ian Malcolm was heard to mutter:
A true mass-market P.O.S. It can only print weak biodegradable objects,
(cant use ABS filament) and the lack of a heated build platform almost
guarentees distortion when printing tall objects.


PLA isn't weak, it's just not designed to handle the elements. A
heated platform does not guarantee against warping on tall parts. ABS
has a tendancy to curl, so a heated platform is required. PLA does not
require a heated platform. Once objects reach a certain height, the
heat from the platform becomes irrelevant. People are even making
complete printers OUT OF PLA.
