The only downer for me is the use of SD cards, instead of the CF cards. Does Sony have shares in the SD card patent holding company?
I can understand changing storage cards if one type has a huge advantage over the other but this change on a whim stuff is annoying. If you upgrade your camera or add another body you ought to be able to have your cards interchangeable in my view....john
I did a little checking on Wikipedia (it's lunchtime, so I'm allowed

) The SD card system is Japanese (albeit, first developed by Matsu@~&%a, which is essentially
Panasonic), whilst the CF card system is from SanDisk, an American company. Sony is a Japanese company and there's some really serious economic troubles in Japan right now. So, buddies will be buddies and help each other... I assume. Hmm... complete speculation. I'm sure there's a better reason. I can understand with the A230 and A330 and A380, as it'll help encourage point-and-shoot users to move up, but for the A550? There's gotta be a better reason. I wonder what the market penetration of CF is at the moment.
SD Memory cards have just become the most popular, with CF cards now number 2...
as of 2004. Hmm... after more googling, nothing. Back to work.
