A:AnswerIt' worth the upgrade if you want a slimmer, faster Ipad. The speed is noticeable, but what sold me was the facial recognition...it's quick and seamless. No more having to find the home button. If you upgrade and have a pencil, your current pencil will not work with this new Ipad Pro. You'll need to purchase the 2nd generation pencil which attaches to the Ipad's side while also charging it. For me the upgrade was a no brainer. Good luck and hope this helps.
A:AnswerYes, you can also login with a passcode. In fact, when the device doesn't recognize your face (wearing a hat, low light, bad angle, etc.) it defaults to a passcode.
A:AnswerAn Apple "pencil" is definitely not mandatory IMHO. When I purchased my 11" iPad Pro, I assumed I would eventually purchase the pencil, even bought an iPad case with built in storage for the pencil. However, until I read this question I had forgotten the pencil even existed! I use my iPad Pro for nearly everything I do and I can't think of a single instance where I was prevented from doing a task because I lacked the pencil. It might be a requirement in some applications but not in my instance.
A:Answer64GB is fine as long as you aren’t downloading everything, carrying a huge music library, and taking huge amounts of pictures. Really if you’re not using iCloud, Google Drive, or OneDrive, it’ll be hard to fill up 64GB.
A:AnswerYes Bluetooth keyboard works just great. ,Logitech slim cover and keyboard self-charges via wireless charging from the iPad! Keyboard battery lasts fantastically long as well. Best choice in my experience. Microsoft Office 365 can be downloaded giving you Word, Excel, PowerPoint. Find them in the Apple Store.
