Flaws in the design of Litecoin..?

[olivia]

I read the following in an article on Litecoin – "because Litecoin is designed to be inefficient on all common computer components (both CPUs and GPUs), a malicious entity needs only produce a single piece of specialized/custom hardware to overtake all the commodity mining systems combined."

I'm not clear on what the specific 'inefficiencies' are, but if they are sufficient this could be a fairly major flaw in litecoin's design. Can anyone explain how this might be true and if so how it would work?
