I am not computer literate.  I know there are tons of options out there and need your opinions on what you all use to do 2 things
1.  Attach to remote to have a bigger screen.
2.  Use to view and work with photos and videos afterwards.

With that said do you use two devices or one to achieve the above options?   Looking for something I can use for internet and work with my drone and portable with enough storage....tall order I know.     Lookin to you all for my options and advice....thanks in advance

Use cell phone to collect data...video and still photos. They are used in cojunction with controllers on smaller drones. Data can be transferred to any computer for post processing. You can also use a larger tablet if you wish...Apple or Android. Check with DJI to see what operating systems and version are compatible.
