Problem to me is lack of featurers.
Bugs can be fixed, however lack of features are hard to solve.

Whether I agree with that or not kind of depends on the feature that is “missing.” If it’s a mathematical function on a programmable calculator I would
be less concerned as it could simply be programmed. If it were a more “fundamental” feature like looping , branching or a PAUSE function,the I’d be more persuadable.
