If you enjoy tech and Science Fiction I recommend "Dvice" and "Blastr" magazine apps. You need to get "Angry Birds" and "Cut the Rope" for the pure addictiveness of these games. And for reading "iBooks", "Nook", "Kindle", and "Kobo" are all good choices and represent the largest book retailers in the world. I also recommend "GoodReader" for document viewing, "Photobucket" for image manipulation, and "Atomic Web" for an alternative to the "Safari" web browser. If you are a hobbyist try "Photograde" for coin collecting and "GedView" for your Genealogy files. There are a lot of additional good apps out there and the above is just the tip of the iceberg. I suggest you click on the "Apps" portion of this forum and read through the entries for a more thorough listing of important, educational, and outright fun applications.
