RSS Reader Quest (do not buy U3 flash drives!)

My quest for the holy RSS grail continues. I tried Google Reader and several other web based feed readers, and they're just not convenient enough. I am addicted to feedreader.
A new version of it does support synchronization to some specified location, which is sort of what I wanted. But now I am hindered by my poor upload speed, and find that this synchronization is extremely slow.

I turned to look for U3 solutions - just install some reader on my U3-enabled USB disk. Guess what? There is no U3-compliant RSS reader (if you don't count Mozilla Thunderbird, which is too cumbersome). Feedreader claims to "work with U3", but it doesn't.

Finally I read in Wikipedia that the U3 format is about to become obsolete, just two months after I bought it.
