Congrats on the new purchase! As for apps I have 5 screens worth of them.
So many great ones out there! Several months ago I made an apps thread so here is the link to it and lemme see what else I can add below the link that I have gotten since the thread...

I like the dictionary ones and have thought about getting the scrabble check ones for when DH and I play scrabble together. but for now i use the dictionary app.
I LOVE my written news apps and they are the most used of all of my apps. My favorite is BBC reader, but when I don't want to read articles as lengthy, I click on my mobile news app. Both were free I believe.
I like my stitcher radio app so I can listen to international news in the morning on my walks with the pooches. I also have NPR mobile, PRI and Public radio apps, all free as well. but I prefer the stitcher one which gives me a lot of choices for news under a single app.
Free memory is fantastic when your phone starts to slow down or apps start crashing. you just click on the free memory button and it closes up some things and frees some memory up so things work better again.
I like vitals view for tracking health stuff
Buzzilions I love if I just want to look up reviews for something.
Urbanspoon has been a help when DH and I cant decide what we want to eat. We let the phone decide for us.
Shake and Spell was already mentioned, but I also like word warp, enigma lite, WS lite and word link. they are all fun and short word games great for killing time when you have a few minutes you are waiting at the dentist or something.
I have DOFmaster for calculating the hyperfocal distance when I do photography.
And if you are going to be doing any traveling, see what is out there in terms of apps for the place you are going. I got an app on Ireland and also one on North Wales for only a couple bucks each and they were very helpful in our trip planning. they actually provided different info than all the travel guides in terms of some transportation options and such.
If you find any great ones not mentioned, let me know. I have room to add more.
