Would be very cool to see this for NYC. Obviously, there's no "center" like Boston has, but if you just considered the center to be the square of 'midtown' from 14th to 57th st, and 8th ave to Lexington, and only drew the lines emanating from outside that, it would work the same.
And have a separate version where everything emanates from the Financial District.
Would be AWESOME for comparing commute times when looking at job/apartment locations. You could even add half the interval between trains, to make it even more realistic for planning.
This would be very cool as an interactive thing where you can select your own center. Hell, it'd be great for apartment hunters who can just select wherever their work is and go from there.
The major drawback of this map is that it gives you no clue as to how to actually get to the nearest subway station, and it doesn't tell you which subway station is close to your destination. By focusing only on travel time it has abstracted away a bit too much of the information that people expect to get from a subway map. (For example, the NYC subway map shows the locations of subway stations with respect to major streets and landmarks.)
Also, in most transit systems, travel time can depend significantly on the time of day you're traveling. Express trains don't always run and the time between trains increases during off-peak hours.
IMHO criticizing this map for its lack of spatial accuracy is sort of missing the point. It's not designed to be in the space dimension, it's designed to be in the time dimension.
The official itself is very good for determining location and the nearest T stop to various landmarks. If that fails, then Google maps is even better.
However, this map is damn good for easily and immediately visualizing how long it takes to get from stop to stop.
I'd guess from your comment that don't likely live in Boston or have spent very little time here.
The way the city is set up, the T lines basically just run out toward other stuff. Only when you are in downtown can you find multiple lines close so most of the time you have only one option if any.
There aren't express trains, but it would still be useful to have some weekend service posted, especially for the green line (of which there are 5 once you get west enough!).
There ARE express trains, they're just not scheduled in advance (for example the b line goes express from bu east to Washington to make up for delays quite frequently).
As a resident of Boston, this is correct except for the regular delays of the Green Line. Consider this map only accurate for the three other lines and add 20 minutes to the map's estimate for the Green Line and you're probably in the ballpark.

I like this for the design, but for something that's even more practical for distance discovery, check out this Chicago times map: http://www.mapnificent.net/chicago/
I would love to see this color-coded with average house/apartment prices --- to see if each arc is equitable or if you can see a pattern ( +10% by the water, etc).
It's not 100% accurate, but it gives you a rough estimate of time to the Hub vs. rent. In general, the biggest selling point for Boston apartment seekers is proximity to the T and time to commute to the the Financial District (near Goverment Center). Areas near colleges (BU, MIT, Havard, Northeastern) are also high rent because college students eat up most of the housing.
Unfortunately it doesn't line up all that well because of the heavy distortion of the time scale map. For example the red area in the upper left corner is clearly the Mass Ave corridor in Cambridge, which in real life lines up with the red line, but you can't see that in the overlay.
Housing prices also depend heavily on a neighborhood's crime rate, school rankings and other quality of life issues which vary significantly even among physically adjacent neighborhoods (at least there are lots of examples of that in NYC). So I doubt you'd find a simple relationship between time from the city center and real estate prices.
But there are many exceptions. For example, Cambridge (red), Somerville (yellow), Chelsea (green) and Roxbury (blue) are all within approximately the same distance of the center.
Distance to a T station, not to downtown. Cambridge and Somerville are considerably more expensive than Roxbury generally. Within any of the neighborhoods you listed, you'll find that rent goes up as you get closer to a T station.
