quien como tú

I have heard the phrase "quien como tú" but I'm not sure what it means in context. Here is a recent example (as best as I can recall): "estás descansando hoy pero yo, no .... quien como tú" What does the phrase "quien como tú" added to the end of this sentence signify? Thanks for your help, Tony

The WordReference forum had a thread dealing with this phrase. One native Spanish speaker said the following: *"Es una contranccion en español de Quien no quisiera ser vos ( o tú) para estar de vacaciones, por eso la frase I wish i were you (para este tipo de frase se pude poner I WERE) creo que es lo ideal."* And then a native English speaker added: *"Sometimes in situations like that, when you are envious of someones good fortune, we say, "Oh, man! You lucky dog!" We also say, "I wish I were you.""*

Hmm, ...quien como tu? I can't say I've heard this phrase before but to me it seems like its saying... who, but you! refering to as if anyone would be resting it would be you!.. so you lucky dog would be quite correct I would think... Mauricio.
