This may have been one idea 5-10 years ago. Today, the Amiga (in all its flavours) is bluntly, irrelevant.
People want a familiar, proven and yes, "boring" system when it comes to computer tech'. They want it to be simple to set up and easy (and cheap) to maintain.
While the x86 part of your arguement fits this, the Amiga part doesnt. Which modern company is going to invest money on an unproven, outdated and obscure platform?
If you want to build a MM kiosk, use any one of the existing imbedded systems on offer, not some Ainc cheapo sourced "Yum-Cha" x86 board running a confusing and overcomplicated combination of Linux and AOS3.x.
In any case, Ainc dont have it in them to make this work. Just imagine the technical support their clients would receive, the Amiga name would go from being obscure and unknown to derission and disdain.
The only future for the Amiga is to capitalise on the people that use/remember it, though every year that market shrinks further, it's probably way past too late?
ie:
-Branded MP3 players and other cheap electronic gadgets and online retro Amiga store.
-A500 in a joystick, hackable like C64DTV, (though the retro kick may be just about over, too late!)
-Amiga classics CDs (done, but piss-poor!)
-Amiga sponsorship deals with lowkey (ie affordable) sporting events, try kiteboarding or wakeboarding ect.
-OS4 ported to x86 as a free distro, with purchaseable apps.
-OS4 could work as a gateway to an online community site (like Xbox-live) with a richer featureset than non-OS4 access.
-Official Ainc endorsed OS4/WinUAE package, with online pay-per-game/app ADF library.
CBF giving away any more free ideas.
