Many people (not only Canon users) use a point and shoot of sorts
(including EVF Long Zooms and Compacts) as well as a DSLR. Many use the
same brand. So it appears that Canon made a good decision to change the
new Xsi from a CF card to an SD card.

I am not sure but I do not think there is any advantage to a CF card and
the SD is less costly.

As long as there is not advantage I am wondering if Canon, on the new
rev of new DSLR version, is going to change all DSLRs to the SD format.
So far I think that would be a good idea.

Any opinions?

My older Nikon D-50 uses a SD card while my newer Nikon D-200 uses a CF
card.

There may be a feeling in some pro circles that CF is better simply
because it is physically bigger. It may also be slightly ahead in
capacity and speed. Though SD cards have, I believe, the better
connection mechanism. For the non-pros, I think that SD is clearly the
standard today. Tomorrow, who knows?

Smacks of indecision, doesn't it? <G>

I would expect that CF and SD cards use the same chips. Cannot tell
about electrical contacts and handling which is also a matter of
personal taste.

Actually, I prefer SD since they seem to become kind of industry
standard.

My Canon S400 P&S uses CF cards and my D200 uses CF cards. Even my
Garmin 2610 GPS uses CF cards. So I'm happy.

I think, because the speed and capacity of CF is always 1 step ahead
of SD, you'll still see the upper end cameras be able to use CF. I
don't consider the Rebel Xsi an upper end camera.

My Garmin GPSmap 60CSx uses microSD cards, which are tiny. Have you seen
that size? I wouldn't want to drop one in a field of grass - impossible
to find I would think! But it's nice that they fit into standard SD slots
with a simple adapter for reading and writing.

Two advantages to CF over SD that I can think of immediately: folks who
have been doing more or less serious photography for some time already
have a bunch of CF cards; and they are a little easier to handle -
particularly for folks with big hands and older folks.

Major technical advantage: CF does not suffer from the same design
limitations and the resulting backward compatibility isses as does SD:
- early version of 1.x limited to 1GB
- later versions of 1.x limited to 2GB
- custom enhancements using 2kB blocks to overcome the 2GB limit often
incompatible with other devices
- SDHC (SD2.0) limited to 32GB at this time. Although the interface
format could support up to 2TB there is no requirement for devices to
support this at this time, probably triggering yet another round of 'buy
a new card reader' when the standard is updated to more than 32GB.

In short: there will be 5 different and not backward compatible versions
of SD within just 10 years.

CF on the other hand has supported up to 137GB right from its inception
back in 1994 with any 15 year old device from back then still working
with the most recent cards just fine.
