I see your point and would like to think Elbox wont put out a product that's the same "real life" speed or less stable than a 10+ year old product.
There should be benefits in quite a few areas, video work, CD/DVD burning, even surfing the net, but it wont be needed for old games and the like which lets be honest is probably one of the biggest pulls for the Amiga and makes you ask do we need it? I guess at this stage any development for the Amiga is great though!
Personally I’m going to wait for the Shark and get one of those as it will add so much more than the Dragon in my opinion.
