I totally agree with this. It's amazing how things change over time. I've been vegan for coming up 6 years and now in my local supermarket there must be 10 choices of soy milk along with rice and oat. Also products such as vegan ice cream and other goodies keep popping up. I also think the variety i have now comes from my own education. When I first went vegan I had no idea what there was out there. I think it's taken me this 5/6 years to find some things.
Though things to change, I was reading a vegan cookbook from the 1980's ( or it may have been earlier actually) where it mentioned vegan products and where to get them, they were really weird and things like soy milk were given with instructions such as may have to mail order.
