Fine, but if it's doubling as an MP3 player (great idea actually, one device to do it all etc) then it needs to run on cards that you can pgrae to 2gb on......you won't get bugger all on 200 meg with the maping you need
That device, that small, with solid state memory of about 500meg for the whole of europe, with SD or similar cards up to 2gb for MP3's, waterproof, bluetooth and so on, and they'd have it made.
