Which of the following best completes the passage below?

Sales compaigns aimed at the faltering personal computer market have strongly emphasized ease of use, called user-friendliness. This emphasis is oddly premature and irrelevant in the eyes of most potential buyers, who are trying to address the logically prior issue of whether___________

(A)user-friendliness also implies that owners can service their own computers

(B)personal computers cost more the more user-friendly they are

(C)currently available models are user-friendly enough to suit them

(D)the people promoting personal computers use them in their own homes

(E)they have enough sensible uses for a personal computer to justify the expense of buying one

(E)是正确答案。(E)和(C)比，更贴近whether they will buy one, 但是我想请教一下(C)从消费者的需求出发为什么不是答案呢？是问题出在"logically prior issue“，"认为有用"是"用起来方便"的必要条件吗？而(C)是说用起来是否足够方便，所以这样选了(E).

如果消费者感觉买来没用，那么方便性还存在么？

很容易理解的前提吧。

反过来说，认为计算机用起来方便的前提肯定是认为计算机有用
