I totally support Amiga, and I hope they pull it off (sorry Akira), but I don't think you should buy an Amiga at this point in time.
I think we should wait and see what happens. AmigaDE looks promising, but I'm not going to buy it until I see that it's actually of any use.
If you want a computer for productivity, then stick with the PC
If you want a computer for games, buy an Amiga 500
Always keep a look out on http://www.amiga.org
