straight out of the 不好意思，完整句子是：the ipad didn't destined to be a runaway product success straight out of the box

把整句话写出来，你这个根本就不是个短语，straight在这里肯定时做副词，修饰一个动作，前面肯定有个动词，
麻烦把完整句子写一下

这台苹果电脑不能成功指派一个直接从盒子里拿出来的产品

是这句句子吧.

straight out of the box:就是指拿出盒子就可以使用的计算机或者软件,不需要装额外复杂的东西.
这里是说Ipad显然不是那些拿出来什么都不用做就能玩的畅销电子产品.
