Well, right now I have Beam Reader installed. There's an update out there, that if I accept, would turn it into a trial app instead of the permanent app it is right now. So, if I get a notification about updates, I have no idea whether I should ignore the notification because it's just another reminder for Beam Reader, or if I should click on the notification for apps I actually want updated.
(I wish I had done the same with Dolphin Browser -- I bet a lot of people who didn't upgrade Dolphin would prefer not to keep getting notifications to update it.)
