Living and working in France has meant that we needed a French computer with €, é, ç, ^, etc. However, getting used to a full stop being uppercase has been the bane of my life. My writing is constantly peppered with semi-colons because that is the lower-case part of the same key. When giving an email address with an underscore in it a French person might say that it is key 8, not realising that the symbols are in different places on Qwerty keyboards.
