Some of the pieces DO work (48dp as hit-target is a good advice, and colour palette etc. is pretty usable). I think it's a good start for all the Android devs (non-designers) who put apps together which are 99% crappy looking. I am quite frustrated however that they do not tell us how to get the same behaviour on older devices - they should release a look-and-feel compatibility library or something. Actionbar is also very inflexible (tabs with buttons in one row, anyone? adjustable tab width?) and making the same code work for 2.x - 4.x devices is just plain spaghetti.
