A:Answer I would say if you want a cumputer go with surface pro or a surface book. But, if you want an iPad go with the 10.5 or 12.9 whichever ever you prefer, I think the 12.9 would be best because it’s the same size as most laptops. I would go with 256gb either way because 64gb isn’t that much and 512 is a little excessive unless you use a ton. Go with WiFi only because you said you didn’t want another device on your plan. I have the 10.5 inch 64 go but planning on returning to get 10.5 256. I would say to get the Apple Pencil because that is one reason to get the pro model besides specs. Expensive, but worth it in my books, have only used once and don’t personally own one, but getting one. Also, with it you can download a photo editing app and edit photos with it. Also getting a keyboard with it I would say is a must. Remember also It’s limited to IOS only it does run windows. If you have other apple products and a computer already and your just using this as a add on go with it!
