Hell, crazy fact about the "600MHz" OMAP3, they aren't supposed to run at that speed. That's an overclock and they're not guranteed to live long at that clock. 500MHz is where it is. So that's another deduction. I am sorry that I don't have a link for this. Sort of in a rush right now, it's somewhere in the eLinux wiki about Beagleboard.
:blink: uh... no. 500 may be optimal for life expectancy, but they're still guaranteed at 600: that's not overclocking. What isn't guaranteed is that they will run at higher clock speeds than 600. My car says it can get 6 L/100km at 80 km/h, but that doesn't mean I can't cruise along at 100 km/h.
It was discovered, however, that most (perhaps all, at least all those tested by OpenPandora so far) OMAP processors were actually still stable at 800 mhz and beyond. What happened (or what is suspected by many, myself included) is that TI realized that their processors are consistently stable at 720 mhz, so in a bid to capitalize on this, they started repackaging some of them as 720 base (instead of 600 base) and charging extra for the 120 mhz "bonus"; a bonus which already existed, it's just that now TI is officially endorsing it.
edit: and regarding "not guaranteed to live long", I won't bother going through the specs to get the exact numbers again, but doing the math, overclocked to 900 mhz, it had an expected life expectancy of 5 years running 24 hours a day 365 days a year. I don't know what your definition of "long" is, but 5 years seems plenty long enough to me.
