The main problem I have with CUSA is the attempt to market something off-the-shelf (Linux + keyboard PC) as a "NEW Amiga". This leads one to be naturally cynical of the underlying motives.
If on the other hand they invest time and actual money in more-than off-the-shelf concepts such as custom cases, then you have to give them some credit for going a bit further than making a quick/easy buck on nostalgia.
Wait and see, I guess?
I remember being a bit wary of Cloanto repackaging the freely available WinUAE emulator and calling it AmigaForever. CUSA could learn a lot by modelling themselves after Cloanto's efforts and motives, or they could just be in it to scrape a quick buck off overly sentimental, nostalgic suckers?
