We're in full agreement. But with 3GHz intel processors, spending a lot of expensive human time tuning an application hardly seems worth it. If new school uses 3GHz processors, old school uses 300Mhz processors, there's a lot of room for bad programming to be competitive. but at least the z990 is getting close to "new school". We can get the best of both worlds...
