CF cards are they on their way out

i notice canons new 7d is using CF

i thought these cards days were numbered

Looking into the wiki article on Compact Flash the main historic benefits of CF compared to other mediums (SD, SDHC, MemoryStick etc); capacity and read/write speeds, have all but disappeared. The only remaining one that I can think of is that, with CF, the controller is on the card itself.

There is the argument that with the 7D being a professional grade camera, and Canon's pro cameras going before it having used CF, that you wouldn't want to annoy those who'd invested in your marque and the more expensive, >300x speed CF cards. In addition to this many pros carry 2 camera bodies, often using their previous one as a back-up should the need arise (e.g. dead battery grip), and the requirement of carrying 2 different types of media takes up valuable bag/pocket space.

IMHO the future is probably SDHC/SDXC cards with built in wifi...

i see there is an sd card with built in wifi already

anyone tried these

There was a TV show about one of those celeb mags a while back (the one run by an Aussie guy with the mohican). In one episode a paparazzo had a wifi sporting memory card that he used to transfer pictures to his laptop in the field.

The Eye-Fi range seems a perfect partner to the emerging 3G tablet market for the on-the-move pro/semi-pro photographer. (It would be over kill for most, though perhaps not all, enthusiasts.)
