the atari name was bought up by INFOGRAMES in 2001/2 , they use it as a games publisher name and have had quite a success with it due to the fact that atari liscenses have been very big and of special games more or less.
but it has nothing to do with the orginal atari team and all atari users can confirm that and they rescent it!.
its like if Ocean all of a sudden started to produce hardware

anyway as we all know, atari was a really big thing in the early 80s to the later 80s with games in the arcades etc + a rather mediocre deal with williams till 1994 or so.
anyway amiga is further, but atari has AGP hacks for their systems , but still no ppc but they have had the coldfire for quite a while now

so its sorta even but seriously atari havent really made a name out of them selves the last years as in the fan base.., they ported a few late amiga games to the atari but thats about it.
cheers
pps:the demoscene is still hw bashing the falcon and i am still impressed , though i expect more in the future when they will get a standarized os for it, its basically a hack n slash os atm (bits and pieces...and as we all know...TOS aint really an os:) )
