Before I was using the built in Internet Explorer 7 reader for my feeds and on my phone using Iliums NewsBreak. I had them split to work releated feeds on my desktop / laptop and feeds of ‘interest’ on my phone but now have them all consolidated on Google Reader. I can access them all as and when required from my phone, laptop or desktop.
Its pretty neat and the added mobile reader makes picking up the feeds on my phone simple and fast considering I connect via a GPRS connection.
If you subscribe to many feeds and like the idea of access from anywhere then check it out.
