One advantage is that a lot of content is only available for TR.
I've never used it myself, but I noticed a while back in Memoware.com that there was some stuff I wished I could read, but it was only in TR format.
One example of an item available item for download, according to
Palm Addict is Wikipedia. A gigantic web-based widi encyclopedia that is supposed to be about a gig in size. (You'll need a big memory card, I suppose!)
I know it sounds useless to have the public create, edit and maintain an encyclopedia, but there's a surprisingly nice collection of info there. Just don't trust it like Encyclopedia Brittanica. Actually, as card storage gets better, I'd like to see Brittanica for PDAs. Only problem I have with that is the same as any other ebook... with proprietary formats and DRM, will it be useable and readable in the future?
I think Hacker shared some thoughts on Widipedia for PDAs here a while back. Can't remember what he shared, but if anyone is interested, you can search the forums. He always has good insights.
Guess I wondered a bit off-topic, but my point was simply that getting TR probably opens up a lot of new content to you. You can browse memoware to get a better idea if it matters to you. And after a major rewrite, I wouldn't be surprised if it's a very nice reader program also.
Anyone actually use TR out there?
