What are the consequences of having W's on your transcript?

I’ll give you the facts:
-I’m transferring out next year from a community college, but I already have 52 completed units. I’m currently taking 15 units
-I already have one “W” on my transcript, but I made it up next semester and it was a 1 unit class
-I originally just randomly chose to be a Business major, but I had absolutely ZERO passion for it.
-A couple weeks ago, I decided to become a Computer Science major
-Currently, this semester, 3 of the 4 classes I’m taking I no longer need at all, and I am also doing terribly in them

So what are the consequences of having W’s on your transcript? Do the consequences differ between privates, UC’s, and Cal States?

Anyone?
