Switched from Bloglines toGoogle Reader a few days ago. Every day I use three different machines with three different OS's (Vista 64-bit on Core2 Duo Desktop at work, Server 2003 Toshiba Tecra M4 Laptop and Media Center 2005 on a P4 at home). Using a client reader is just too clunky when you read feeds on three machines. Sure there is remote feed storage etc etc - but it's still slow and clunky. Bloglines was the ideal solution - but Google's reading experience (font, navigation, feed management and frankly: performance) has made all the difference.
