Hi everyone. Am a computer user for over 20 years (Mac) but new to Android as I just bought an Android tablet for web and PDF reading on the couch at night as the iPod is too small. Am used to iPhone/iPod and find the new tablet works much the same, so no problems there. I am using Wi-Fi from my router, and want to keep my system (and connected computer) safe. Have downloaded several apps from Google Play and notice they ask for permisssions, some of which look cautionary (contacts, network-does it access private router/network / info??) as opposed to the Apple store which do not request permission. I figure since people are downloading from there, then these must be standard requests...maybe the apple apps are doing that too but just not asking me since apple has their approval process before they accept it to their store. Are these OK and anything I should decline? What is the "pure Android experience" I've seen mentioned? On the Apple devices there is a nice feature where when you browse the internet and have reached the bottom of the page and want to get quickly to the top, you just touch the top of the window and it brings you there. Is there a way to do that on Android? Should I have virus / malware protection installed, and what one is good? Why does the tablet say Adobe Flash cannot be used/installed? I thought at was one of the reasons to not have a iPad! Thank you!
