I don't commute anymore, but I used to take the Seastreak ferry - the one that crashed into Pier 11 today. It sucked. It was like a 15 minute drive to the ferry, then 45 minutes on the boat and then a 5-10 minute walk to my office. Plus I had to build in extra time to park and make sure I didn't' miss the boat so it was like an hour and a half door to door.
When I lived just a few miles from the city in Hoboken I used to take the bus from my corner to the PATH and then walk. That was about 45 minutes door to door.
If you got nothing to bring to the table - don't even bother sitting down.
