First off,thanks for all who responded and offered such detailed, valuable advice. ^

Confusing isn't the word for the documentation and tech support provided by the laptop manufacturer (Fujitsu - somewhat surprising as the documentation is otherwide pretty good). The manual only stated that SD cards could be used in the card reader - no capacity specifications or options were given. My first call to tech support ended when the person did not know what an SD card was (even as I heard the reference flip charts being furiously turned). The tech on the second call at least knew what I was talking about - she stated that there was nothing in the documentation specifically about capacities, only that 1GB and 2GB cards were options that were listed on her accessories list.

Searching online, I found another Fujitsu accessories list that matched what the second tech said about 1GB and 2GB being offered as options. I also found anecdotal information on other manufacturers' sites that seemed to indicate that many internal readers don't support the high capacity flavor.
