In my one month's use, my essential apps:
Essential:
Newspaper and Magazine Apps (Its really nice to look at a lot of the newspaper and magazine apps on here. Beautiful spreads. I read the Washington Post when I get up and I subscribe to Food & Wine and NewsWeek.)
Notability is good, but I'm probably buying GoodNotes in a few minutes, just because I like the layout of having notebooks for different subjects.
PDF Expert
Pocket Informant (Planner)
TV channel apps (Great if you've got a cable at home. I have HBO, FX, Food Network, Comedy Central apps and more.)
AllRecipes (Gotta eat
)
Reddit
Podcasts (I was never a podcast guy, but the speakers are so good on this device. Nice to just play one of the many podcasts on a particular topic while browsing.)
Games:
I'm more of a puzzle guy. I really have to hand it to the developers of these LEGO games though. Very addictive gameplay. Just bought The Force Awakens.
I play Miniclip Pool a lot. In fact, I just rage quit out of my Holiday Championship matchup.
There's so many good-looking games it's overwhelming though. I have several, but don't really play them.
Standing by for more game ideas.
