I've been using an Olympus C-770 for 3 years, just got an E-410. I'm generally pro Olympus, but the XD card gives me problems I NEVER encounter with SD or CF. I've used 3 different card readers on two different computers (Windows 2000 and XP). Sometimes it won't read at all, sometimes VERY slow to read, sometimes a picture or two will be corrupted - the bottom half missing, or digitally jumbled. It leads me to believe there's something inherently 'unstable' or 'Hinky' with the XD 'platform'. Thank goodness my new E-410 has a slot for CF as well.It doesn't happen all the time, just enough that I can't trust the XD with important pics. (and every pic is POTENTIALLY important)
In the C-770, I never used larger than 128 meg, and it occurs less with that,than with this new 512 card in the E-410.
