I would like to hear opinions on the best RSS reader for flyertalk.

I'm not very experienced with RSS, but here are the features I would like to have in a reader:

1. offline ability. I should be able to download everything I want from FT and have it stored on my disk, so I can catch up on all the forums while flying. It would be even better if I could write a message to post in offline mode and have it upload once I connect up again.

2. forum hierarchy. I would like to see everything in a similar forum structure as I see it on FT.com, and be able to see all threads within the forum. I should see new threads and have the ability to subscribe to them (mark them for download). Even better if new threads are automatically subscribed by default, but I can "unsubscribe" them. That way I can suck down everything new (including all new threads), store it for reading offline, and then on an airplane I can read through them and unsubscribe from the threads that are no interesting.

3. some ability to sync between the desktop and a Windows Mobile device would be nice. the idea is that whether I use the desktop or the handheld device, I would be able to download the new/subscribed threads, and as long as sync I could switch between either reader without even "losing my place" in the threads. (I mention Win Mobile and not Palm because I am Win Mobile based).

... I guess many of you with more RSS experience can add more requirements. So let us know what you think is important, and also which RSS readers you recommend.

Thanks
Ron
