Even on the desktop, I don't use reader.google.com
, I use Feedly (extension for chrome/firefox, though I never understood why you have to use the extension, it's just a web page) and love it. On iOS, the feedly app is good too. The Android app though, is just a port of the iOS app for the most part. Performance is bad, especially the internal browser which is an unnecessary construct on Android. It takes extra button presses to launch an article in your browser of choice rather than the poor implementation of a browser in the app.
On my iPad, I prefer Reeder to Flipboard/Zite/etc. I can't wait to see a massive redesign of Google Reader, as long as it still allows third party apps to sync feed lists, read/unread status, stars, etc. Maybe I'll actually use Google Reader itself rather than just using it as a common place to store my list of subscriptions!
