Hi, I'm not sure whether or not this will be of interest to anyone, but I've compiled a diff of the packages available in i386 compared to amd64 (if anyone wants to try the other without lossing essential packages). I haven't been able to find a similar diff online, so maybe this someone will find this useful.
