http://www.appleinsider.com/review.php?id=4If I had to compare the performance of this machine -- while running applications under Rosetta -- to a another Mac that I've owned, I'd say it's comparable to the single-processor 800Mhz Power Mac G4 it replaced on my desk -- and that machine hadn't been reformatted or maintenanced in years. My 1.33GHz iBook G4 is noticeably snappier than the new iMac, and that's a real disappointment.
I cannot emphasize enough how much Rosetta slows the entire machine. With PowerPC apps running, the whole system is useless. I cannot imagine running any processor-intensive tasks inside Rosetta -- the experience would be nothing short maddening. In fact, I think you'd be hard pressed to get anything accomplished.
Enough said.. Pettymys. Tosin universaalit binäärit tekevät tuloaan sellaisella vauhdilla, että hyvällä tuurilla en itse Rosettaan joudu edes turvautumaan jahka ensimmäisen IntelMacin saan hankittua.
