normally there's also a 37 gb version which has the same specs (expect size) as the 74 gb version

but i haven't seen it in the shops

=36gb version. bits and bytes and giga, mix em up and you can make 4,7gb out of 4,35gb :-)

nope

when the 74 gb version was annouced they also mentioned a 37 gb version with the same specs

the 36 gb version was already a year old then
