As goes with the vast majority of questions asked on this forum, it all comes down to personal preference. I currently have the 9.7" iPad Pro with Apple Smart Keyboard. I'll soon be upgrading to the 12.9" iPad Pro 2nd gen. Personally, I purchased the ASK with my 9.7" for the odd occasion I would need it. With it being a smaller device, the keyboard didn't add too much bulk and gave the me physical keyboard whenever I needed it. I would admit though, having had the device for a year, I rarely used the physical keyboard and could have easily done with the onscreen keyboard when the requirement arose. Now I'm soon to upgrade to the larger 12.9", I think I'll go with the Apple Smart Cover for when I'm mobile and use an old Apple Magic Keyboard when I need it (non-rechargeable), which is always when back home. What is your preference? I didn't mind in the slightest typing on the smaller keyboard, I'm quick to adjust to the smaller size. With that 12.9" having the larger onscreen keyboard, I'll manage no problem when away from the house using that. If you have upgraded from the 9.7" to the 12.9", what has your experience been adapting to the larger onscreen keyboard?
