Hi, I'm brand new to Apple and the IPad2. I'm trying to learn the "culture" and the methodologies of the "Apple way of doing things." One frustration is not knowing "if" and "when" an app might have an interface with my PC! Have many years and $$$ invested in the PC platform because universities generally adopted the PC OS back in the 1970s. May some day buy an Apple laptop, but not soon. So, are there any clues to look for when looking at productivity apps that sync with my ICloud and/or Dropbox on my PC platform ? Many thanks; I'm looking to learn from all of you how to use effectively my IPad2!
