The theoretical maximum for CF is 133MB/s.Definded Spec for SDHC/SDXC is 106MB/s max which is pretty compareable to actual CF. The difference is: SDHC/XC are pretty wide spread and loads of notebooks/netbooks that were build in the last year already have readers for those.
The first CFast devices made by Pretec were 160MB/s.
The theoretical maximum for CFast is 375MB/s.
But the Point for 60D having SD instead of CF is Eye-Fi. This feature is, at a closer look, the most impressive step canon took. They kill the need of buying an expensive wft and indirectly include Geotagging by just giving the User access to use Eye-Fi-Cards. So you can choose to buy a wft-grip for about 500$ or buy a battery-grip for 200$+150$ for an eye-fi pro.
In my opinion this gives 60D a (or even two) feature(s), 7D is missing: Cheapo-wft and Memorycard and Battery-Grip together for about two thirds of the original-wft solution. (without having the need of a battery-grip at all to use this feature). And another 100$ savings when using the geotagging-feature.
Comparing the prices of 60D and 7D considering these aspects, gives another 250$ savings by buying the 60D.
