Some people think Amiga is a CPU or Amiga is some special "custom" chips, or whatever. To me, Amiga is the user experience. What the GUI looks like, and more important how I interact with it. It multitasks. I find it agreeable to use rather than an awkward thing to fight into submission.
For those that demand a 68k, you're frozen in time. So are the "custom chips" zealots.
While new PowerPCs still come into being, such as Freescale's exciting new AMP series, PPC zealots are also in an awkward position due to the difficulty in getting them in a form that a) runs AmigaOS and b) we desire. (ie a laptop in my case)
And while ARM doesn't seem to come in a desktop board (that I'm aware of anyway, perhaps I'm just ignorant), we could have them with similar difficulty/expense as we get our PPCs in. But ARMs are already in netbooks! And they already dominate tablets, for anyone who wishes for a REAL Amiga tablet. Not one of those phony things that are Amiga in nothing more than the sticker on the case, however "legal" those stickers may be.
