You seem to be mixing comparisons again. You can't compare CS2 (which runs terribly on Intel Macs anyway due to Rosetta) on PC to CS3 on Mac. Tests show no difference in opening speed for CS3 between OS X and Win XP on the same MacBook, for example (which is actually a little surprising since the Windows drivers provided with BootCamp are pretty poor, especially disk performance and startup time should be disk constrained). Here are some tests (using similar MacBooks running Windows XPsp2 with Apple BootCamp drivers): http://hansv.com/cs3/ http://www.circuitremix.com/index.php?q=node/9 You can see that in the first of these tests there is a marked difference (about 50% in favor of Mac OS) in actual benchmark time for the first run of that benchmark. First runs are, by convention, discarded for this very reason - things like boot status (starting the benchmark before the OS is really completed booting), disk caching, first-run virus checking, etc can all dramatically affect performance on first runs but never again. The subsequent run is much more even (running about 6% faster on Mac OS). OS X seems to lose about 45% of its speed but I doubt that's linear. ;^) Windows seems to provide pretty even performance across the tests. It's a shame because another 10 or 15 runs, averaged, would have given us a much better picture. The other test, using a different benchmark and (I think much more importantly) more RAM, shows that XP beat OS X in performance by over 25%. I would bet (an educated guess, nothing more) that this test simply shows that XP makes better use of Large amounts of RAM better than OS X (although filters in and of themselves tend to be more CPU constrained than RAM constrained that data has to get to the CPU). I would guess that the performance difference would disappear (or reverse) at 1 Gig, but of course I'm not sure (but OS X does tend to use smaller amounts of RAM more effectively than XP). It's impossible to come to a conclusion from these two tests. But I still think that actual usage between the two platforms on the same hardware would be a wash. Computers spend much more time waiting for us than we do for them. Of course some people would argue that similarly configured Macs and PCs are NOT equal simply because the Mac retains a price-premium. They would rather test similarly _priced_ machines, which, at this point tends to favor PCs since at any price point you can almost definitely double the RAM or up the proc speed on the PC. Others would argue that the quality of Windows drivers provided in Bootcamp favor the Mac - the "homecourt" advantage and all - and would still prefer similarly configured machine optimized for each OS. But the bottom line is the same as I've always said: you'll be more productive using what you're more comfortable using. A Mac user will be more productive on a slow Mac than on fast PC and vice versa. Benchmarks test the speed of the machine, not the user. To my knowledge nobody has done a task-based analysis between CS3 on Windows and CS3 on the Mac and I doubt anybody ever will - it really doesn't make much sense.
