For myself, I can say that if I get the cash, I am most certainly interested in this piece of hardware.. It´s much cheaper than to buy an A1, and you get most of the stuff anyway..
Sure, you can´t run OS4, but you can play movies, surf the web, download stuff, use USB stuff, get a sound card, and so on... All depending on how many PCI slots it will have, ofcourse...
But it still sucks that you cant promote the original Amiga A/V to the graphics card.. Major drawback if you play classic games that hit the hardware... :-(
