3" floppies were not uncommon in the UK. As well as Amstrad (both the CPC 
series of home computers and the PCW word processors [1]), the Tatung 
Einstein used them. And I've seen at least one 3rd-paety disk drive for 
the BBC micro that was 3".

I find the 3" disk to be mechaniocally superior to the 3.5" one. The 
shutter on the latter is a very poor design (as anybody who's had to 
strip a drive down to extrace a mngled shutter will confirm.)

[1] They wrre a lot more than electronic typewriters. They were Z80 based 
ocmputers that ran CPM+ (IIRC) and which came wth a word processor program.
