Like vs Such as

From http://gmat-grammar.blogspot.com/2006/06/like-vs-such-as.html

What's the difference between like and such as?

Common mistake we make in there use -

Can you buy me some fruit like apples or pomegranate?

Why the above sentence is wrong?

Use of like in the above sentence mistakenly suggests that the speaker does not wants apples or pomegranate, but rather some other fruit that is similar to apples or watermelon.

In GMAT, like means similar to, and such as means for example.

e.g

Can you buy me some fruit like apples or watermelon?

In GMAT, this sentence implies that the speaker does NOT want apples or watermelon; instead, he prefers some fruit similar to apples and watermelon.

Correct - Can you buy me some fruit such as apples or watermelon?
Apples and watermelon are examples of the type of fruit we want.

I would like you to buy such fruit as apples and watermelon for me.
This is simply a variation -- notice how such and as are separated.
