You'll find that as time goes by, the smaller cards fall by the wayside. Try finding a 1GB card now, for example - probably can't do it. It's pretty hard to find 4GB CF cards now; 8GB will be the minimum soon. Part of this is being driven by the underlying technology: whereas once it took N of a low-density chip to make a given capacity, now it may take just one with current densities. When the next fab line becomes operational, it'll surely be higher density, so the capacity of the products will become greater, whether you need it to do that or not!
