Fave apps

These are the apps I am obsessed with:

-Draw Something, Scramble with Friends, Words with Friends, Sudoku

I primarily use my iPad for college and I LOVE Notability.
I view converted PPTs, draw diagrams, type letters, and just doodle on it.
It's so entertaining!

Dropbox is another fav. Makes sharing files between any computer and my iPad super easy.

Finally, all Big Fish Games are great. They are brain teasers and stuff like that. The full games are expensive (like $5-$7 each) but they have very long free trials I use.
