Except you can only get that in a few places in the city and have to get to those places. You can get a subway just about anywhere, and connect to get to kennedy fairly easily.

You also now have to get a LIRR ticket (as one of the news stories this morning said the lines were way too long to get a ticket and make the train, so they paid more to purchase it on the train), more money.

If you are near one of the places you can get a train, then it's probably better. If you have to travel to get to one of those places, then you may as well stick with the subway.

They need something that goes from the airport to the city without two or three transfers. Get me to Penn Station or Grand Central direct from the terminal, and that's a good thing. Have me take a subway to get to the LIRR, then purchase a ticket, get on the LIRR, then purchase another ticket, and get on the Airtrain, and I may as well have just driven like I usually do, the Avistar van drops me off right in front of the terminal.
