Great to have new users in the amiga community IMHO... that is one myth that is still around. Oh,, another one, ISA slots in the A2000 is not electrically connected to the Amiga so u can not attach ISA network cards to it. :-)
But you do need the Bridgeboard or this other guys Zorro card (forget his name) in order for you to make use of ISA... so maybe that's where people get confused.
And yeah, compatibility is great with the 060. When I had one, never had a problem running anything with it. Games wise, WHDLoad ensures awesome compatibility as well.
