A:AnswerDepends on what your Grammy will use the iPad for. I do the usual plus some graphic design. Found the 10.5 was perfect for my needs. The face recognition was beyond what I needed. The 10.5 is fast, smooth and I love it.
A:AnswerYes, it has a on board keyboard screen that pops up when typing or you can buy a hard keyboard to attach if you must have more than the screen keyboard
A:AnswerThe IPad 64 is on sale now for $499. at Best Buy, I will be buying one tomorrow to add to my 2018 IPad 6th version I purchased for $249.00 on Black Friday. I always stay one version behind on the Pro version.
A:AnswerI called them and they talked me through moving my data from my old IPad to my new IPad Pro. I would suggest you backup your old devise before you call because it only copies the information from the last update.
A:AnswerGoogle iPad pro comparison. The newer model, I believe has upgraded processor (A9x vs A10x). Newer model may also have twice the ram. Not sure you will notice big difference in everyday use. Apple quotes 30% faster.
The better decision is screen size. You should go to B.B. and hold them. IMO, the 12.9 is too large for portability in the field (to carry around and use mobile).
If going to use sitting around, larger pad might be fine. I didn’t look at screen quality for the larger screen. I would assume that apps scale to the larger screen, and I don’t know if that will pixelate on the 12.9. I haven’t noticed issue on the 10.5 screen.
