None, but they usually ship with 16, sometimes upgradable to 32, and these days often no SD slot. The Nexus 9 is 16/32 with no SD, the Nexus 6 is 32/64 with no SD. The Air 2 and 6's are 16/64/128 (though the 16GB is a bloody sham, especially when the next OS will most likely require even more available space than iOS8's already humongous 5GB for OTA) (it was really funny seeing the proud 47%-a-month-in graph when iOS7 was at 71% a month in: http://fortune.com/2013/10/15/mixpanel-apples-ios-7-hit-71-p...)
No SD I can live with, but max. 32GB on a tablet (where you are like to store larger apps/more HD media) is crazy. My 32GB iPad Mini can be a bit restrictive at times when travelling - 1.07GB TV episodes means I can fit a set of 720p TV w/ maybe enough room to spare for a couple of movies.
