My vote is for a NATAMI based new Amiga running AOS3 or AROS-68k. It should be able to use all the latest technologies, USB, SATA, DDR3 RAM, GIG Ethernet, 802.3N Wireless. Whatever OS is chosen should have a future map including 64-bit, multi-core, Tablet capability etc... I know this is a tall order, but one can only dream.
Once fast(er) 68k hardware is available the community really needs to focus on developing a decent standards-complaint web browser for AOS3 and/or AROS-68k. I'd say that would take precedence over 64-bit processors or even some of the more commonplace performance hardware in circulation. Whether that can be taken care of by programmers in the community or through bounties will need to be determined. Netsurf looks promising.
Once a user can surf the web and play streaming media from the workbench there will be more incentive for a user to use a "Numiga" in the first place.
If we're looking for a maxim here, it's this: "Create 68k Amiga hardware that enables one to use the Amiga as their main *personal* computer today"
Most of the people posting on here are Amiga diehards. They run Amigas partly for the pleasure of saying they still do so. Projects like Natami will allow the Amiga diehard to die-harder. It's like putting another water-tight bulkhead in the Titanic.
Natami will buy the Amiga time, especially with the web transitioning to the resource-hungry HTML5. If Commodore USA wants a part of the market they should produce decent cases for Natami. This will require them to get involved in the Natami project and get input from the fanbase ...something they have not had a sterling track record of. If Commodore USA can produce a quality case for Natami, people will buy them. It really is as simple as that.
