I've decided to go independent, more or less, on my Mac and iOS devices. On the mac, its
Vienna, and on iOS its
Newsrack. Both of these can have feeds added independent of an aggregator. There's also a Newsrack for Mac but I dont think theres any sync between them. If there were, I would look no further.
As an aside, for those of you who run Wordpress blogs, there is a Wordpress reader which can import your [G] feeds (well it can import any .opml or .xml formatted feeds). Its not bad. I still prefer Vienna, I can get the number of articles I want, instead of the restricted numbers on some of the current web services.
