That was my approach for ages as well. Now I do use a couple of apps on the iPad for RSS, but it took a long, long while for native apps to match up well with the web app.I love it too, used it for a year now, got tired of this hard to figure out and bad UI's on the app store a long time ago. Good choice and free ;-)
Hmm, that's a novel approach. I find that really good web apps that match native apps are very rare. One that looks promising but I haven't had a chance to try yet is Swearch.Before I download anything besides games, I always check if it's available on the web first, even if it's free, i rather save space for music and games.
