An Amiga in a Joystick , AllInOne is NOT interesting for me ... But it might be sellable to some markets ...
Id rather have a A1000 or CDTV like box or possibly in the size of a MiniMig, with possibility to connect a keyboard and possibly 2-4 bluetooth competition pro's :-)
So to put it short, a nice flat A1000 box (maybe smaller though, maybe just the size of a minimig), with applicable ports for at minimum joysticks, keyboard, usb, SD/-HC would be my wish, a small or larger SSD and Action Replay ?
Bluetooth gamepads or a retooled comp pro, and atleast regular ports for keyboard and mouse is essentials.
Imagine just having the box by the TV / LCDTV and 4 people playing that old car game (I cant remember the name of right now, the multiplayer one) on wireless bluetooth gamepads ! :-D
That would surely sell to some retrofans and others who remember the Amiga, and then just grabbing the box and going upstairs, connecting it to your regular keyboard / mouse setup by the monitor .. !
Demo, tinkerer coding would be a main point for a CloneA for me, so a keyboard is neccessary.
