The public beta spent too many cycles drawing the pretty Aqua GUI. After about 5 minutes of "cool!" the transparent layering turned to "how can I turn it off?" Still the underlying guts are real Un*x so one way or another traditional Unix apps will be able to run side by side with traditional Mac and Modern Mac. > Now, I know that I'll have to get VirtualPC or RealPC for this > thing, for the few programs I need to run that don't have Mac > equivalents -- does anyone know how well they perform on a G4/500 > class machine, relative to actual x86-based hardware of various > speeds? Depends. Disk and network I/O are something near full Mac rates. Gut feel is other things are something better than 1:4 CPU clock cycle ratio. I run Microchip's MPLAB PIC stuff on a 210 MHz PPC 604e. Its faster than getting up and stiting in front of the PC. :-) Then again MPLAB is a 16 bit Win3.1 wrapper on DOS executables. Had to bump their default 30 second timer as lately my code has grown so that it takes nearly 60 seconds to assemble (1400 lines). Were I to actually measure the difference between a P-II 450 and the 604e 210 expect it would be the worst case example. Bought the VPC 4.0 upgrade for my new gigabit G4-400 but have not moved onto it yet. Still waiting on the TiBook. -- David Kelly N4HHE, dkelly@hiwaay.net ===================================================================== The human mind ordinarily operates at only ten percent of its capacity -- the rest is overhead for the operating system.
