OSX might be acceptable to some on slower machines but you're going to want a very snappy OS coming from the windows world. 10.1 seems to do the trick but we don't really know what will be needed for 10.1 plus native versions of the big apps (filemaker, photoshop, quark etc...) as many of these won't be available in a mature form (preliminary bugs worked out, minimal driver issues, you now, somethiing a little beyond the more like 'final beta' versions it has now become customary for software companies to release as complete shipping product)
My typical skepticism makes me think that we won't really know what's needed for OSX use untill not only OSX but all the major apps too have been out for a few months. Looks like you'll need a minimum of 256MB RAM (with 512 to be sure) and a 700-800Mhz Cpu. The older superdrive 733's and DP533's in the lab seem to be OK with OSX. It doesn't seem to me like any of the current laptops will be a 100% lag free in OSX, so I'm waiting on that, but if an 800Mhz iMac G4 is close to a 733PowerMac it should run fine.
I'm not sure why (or I cant articulate it properly), but I really think that OSX was concieved with an entirely different performance metric in mind. Something like G4's about twice their current speed, or scary fast (as yet unseen) G5's. As if it needed to run decently on the current generation to kick start compatibilty, drivers, apps, developer and user interest... etc etc but that it is really intended for something we haven't seen yet. <img src="graemlins/hmmm.gif" border="0" alt="[Hmmm]" />
