Adobe to lay off 600 workers

Ouch, that's a pretty big cut :-( The biggest in tech since KLA Tencor in mid November (okay, only a few weeks, but with the pace of change at the moment, still a big deal).

Adobe are also not going to exhibit at the next MacWorld - some real cost cutting going down.. http://www.macrumors.com/2008/12/03/adobe-not-exhibiting-at-...

Are these engineers or just marketing types?
