I agree that it would be impressive but why on earth would you want that much memory in it? 
Your right, it is likely that I will never use that much RAM, besides, I purchased the RAM on ebay for someone else, just put one of the sticks in one his A1200's. Never have I seen an Amiga with that much Fast RAM, so, out of curiosity, I would have liked to have seen an Amiga with the same amount of RAM as my Athlon. Oh well, looks like thats never going to happen :-(
Thanks for your input guys.
