Sunday, mneme and I went to Datavision and asked what pdas could read my card. The guy we talked to took us to a T|X. This one recognized my card and could open not only the doc files, but also text files. And, while I still couldn't select a quantity between a paragraph and an entire memo, I could select exactly as much as I wanted from a document open in Docs to Go. So, we shall see.
Meanwhile, there was a lovely little tablet for about $1600 that mnemex and I both lusted after, but both decided to pass on for now.
