There's no wrong with using the smith machine, as long as you don't injure yourself.

I'd either do free weights, or use specific machines.
Smith machine simply doesn't suits my workout. I feel damn weird when I was trying to squat using it last time.
And most people don't squat properly in the smith machine anyway... just half squat.

Most forumers here don't hold the smith machine in high regard.
I'm not sure whether I want to encourage you to try free weights... it might be good for you, but that would mean more people queuing to use the power cage/squat rack. =P

Anyone tried doing deadlifts using the smith machine before?
I'm damn curious to see how it's like. X^D

They say the shortest route is to lift straight up mah!

Understood. I know anyone with a common sense wouldn't try it. But since this is a Smith machine thread, maybe some not-so-well-informed people might have tried it. X^D

You couldn't be serious, right?
