It's actually astonishingly addictive once you have it. for me, it's kinda the icons (although, I'm not actually using them all at the moment) but mostly, I love NOT SEEING ADS EVERYWHERE. Srsly. They drive me nuts too and with a paid account you don't see any of them anywhere. (For example, I'm currently not seeing your ads.)

Alas mine runs out in ten days. Oh well!
