I added the AwesomeNote app a few weeks ago. Has REALLY helped get me on track with regards to organization and creating a 'to do' list that holds me accountable to those things that really HAVE to get done.
Angry Birds, though, is a GREAT time waster if that's your goal. I can get sucked into that one for a good part of the day.
There are only three apps I use on a regular basis. One is a note app to keep up with my to-do list. The second is a grocery list app, which is much more convenient than carrying around a pen and paper at the grocery store. The third is the Weather Channel app since simple tasks like scheduling a ride or buying hay often revolve around the weather.
As for junk apps... Angry Birds is my addiction. Other fun games include Ragdoll Physics, Cut the Rope, Plants v. Zombies, DoodleJump, and Rat on the Run.
thanks for the suggestions I did download Angry Birds & find myself losing track of time with that one I like the to do list app as I'm a major list maker, thanks for the tip, I didn't know too about the grocery list app.
