I don't think laziness or lack of time is a good reason to use an
autorouter or 4 layer boards.
You'll spend much more time troubleshooting and stuff if you don't
know your board very well, and even more with those internal layers.
I'd only use 4 layers if it's absolutely nececcary for the design, and
I never use autorouters.
Anyway, each his own, but I could never just autoroute a board on 4
layers and send the ugly mess to production jus to get it done. With a
hobby it's usually the making, not the getting it done, but maybe I'm
just old fashioned.

Also, even though I use a lot of SMD I don't save as many drill holes as I'd like due to all the extra vias that are used merely to hop over other traces. I'm convinced that a 4 layer board will reduce my via count significantly.
