I’m kind of on a budget right now but I want a new IPad that is current release, will not be outdated soon, and good for email, Internet, YouTube, and word processing. Which model and WiFi or WiFi + cellular ? How big of hard drive for lots of scanned photos. Can I print from IPad and also hook up to my compute external hard drive?? Do you feel I need an IPad if I currently have an iPhone 7 Plus or not? However, like the larger screen.
