Jim Hamm found an article that recommends 10 apps that you might want on your iPad. He did not realize that his iPad does not have a calculator. He just uses the one on his iPhone. He does miss the ability to save items to a 'Documents' folder in his iPad, like the one on his Mac. He wonders if Evernote could assume that function? He will find out. He has not found any particular need to have a PDF reader app on his iPad. He seems to be able to open a PDF document fine without another app. His tendency now is to minimize the number of apps on his iPad, and delete those that he does not use frequently, if at all. This helps to reduce the number of updates to apps, which he finds to be a pain.
