as a few of you have pointed out, i'm at the point where i can't really stand to browse without an adblocker of some sort - and so use a combination of adblock + ghostery. for those that may not be aware, if you flash your router with tomato/dd-wrt/etc you can install an adblocker/host script which will allow all mobile (iphone/ipad/android/etc) devices to browse relatively ad-free when connected to wifi.
