If you're going to keep this iPad for many years, then the new Air 2 is the one to get. 2GB of RAM means this bad boy is getting updates through at least iOS 11, maybe even 12. The 1GB devices will trail off sooner. Otherwise if the Safari tabs problem has never been an issue for you and you upgrade regularly you can probably wait. But that screen protectorcan't you just carefully remove it and apply it to your new iPad? I did that for my mom once. The key when applying screen protectors is to turn off all fans and AC systems in your house and let everything settle down for 30-60 minutes. Get a freshly hand-washed microfiber cloth a little bit moist and wipe down the new device. Use scotch tape to peel the old protector off at a corner and remove the whole thing. Slowly bring the protector down onto the new device at the bottom corners and align the home button, then guide it along the side with the edge of your finger. Watch as you slowly place it down for any pieces of dust that cause bubbles. If there are any, pull back the protector slightly and take a piece of scotch tape and put it around your finger and dab it up gently, then try again. Repeat until down all the way. I'm not sure how the glass ones work though, but I imagine it's possible.
