ยง Arguments for little endian

Say we wish to store 100 200 300 400 . In little endian, this would be stored as: 
ix:   0   1   2   3
val:  400 300 200 100
An interesting theory for why this is good is if we want to treat this 4-bit data as 1-bit data, we want the subarray [400]. It's easier to directly acess in little endian as just data[0], instead of in big endian where it would be data[3]. So, storing stuff backwards makes it easier to chop off the LSBs data, since that's the suffix .
