@nmb: That's why I prefer Chrome over other browsers (IE, FF, Opera, Safari). It has a waayyyyy better memory handling than other browsers. in FF I had to restart browser every few hour, but in Chrome memory remain same after 10-12 hours.
I've also 18 Extensions installed, and here is memory usage.
I've always an eye on my RAM - CPU - I/O as Process Explorer is minimized in my tray with all Icons showing, all I've is 2 GB ram, and using these services like this in browser or you may call 'in the cloud' is way faster and easier and lighter for me.
