I always find the "underpowered" statement curious...
It all depends what you want to do with it.... If it has enough power to do what you want, then it's not underpowered... :-)
I have a tablet I use to watch videos, read books, and check some websites/e-mail...
It's 800Mhz with a wimpy 3D implementation. Some games play badly or not at all...
But it's not underpowered, because I didn't intend to use it for those things..
Now, my gut feeling (which is terribly biased and not fair, but too bad :-), is that Amiga is 68k, and I haven't been interested in PPC...
But I have to admit, the netbook and possible price point is at least making me think about my definitions a bit... ;-)
