Commuters from Monmouth County, NJ to NYC or Philadelphia - what are the best public transportation options?

Question

I may have to work in NYC or Philly. I've been to Philadelphia once in my life, but it's a good-sized city and there must be public transportation to and from there, and within the downtown area itself. Is train better? Buses? Is there a price break for commuters? Inside Philly, how good is the local transportation.

I'd prefer a train if possible (easier to use my laptop) but I'll do what's necessary.

I know Manhattan well, so I know how to get around there, but the only time I went to Philly I was 9 years old, and obviously I didn't travel much locally. (I think we were there for a wedding.)

Thanks!

SEPTA is Philly's transit system.  They serve some parts of NJ as well.  Look up their website.   If they don't go to where you are, check New Jersey Transit.
