Vintage-Computer.com,
a site dedicated to the vintage computing hobby with history, machine information, magazines and more as well as a forum for discussions of interest to the vintage computer community and a marketplace for buying and selling vintage computing and gaming items.
Classicamiga.com,
like the webmasters themselves put it, your guide to everything Amiga.
LundXY.com,
home of Morten Lund, the "arch-angel investor" as the press once put it in an interview. The site is actually his personal blog. Very inspiring to read how he feels after losing so much money at once, talking about risk being the key and not money...all this without remorse. As he put it at "Le Web 2008," only people who are born rich have a problem with losing.
