I own a first gen Air and was determined to get the 12.9 Pro back at its second gen announcement. I played with it in a store and loved it. A couple of weeks later, I played with the 10.5 and thought it physically was more appealing. it made the 12.9 look like a pizza box. I thought that I might as well get the 10.5 since I'm still going to use my MacBook Pro for school. So, today my gut was telling me to go back and play with them again. Now I'm all for the 12.9, I can't with myself. It's quite funny because when I hold the 10.5 vertically it looks great but horizontal it looks really small. you have to look closely to realize it's not a 9.7. It feels great to hold with one hand, but I think I'm gonna rip out my hairs if I'm going to play around with Procreate while having YouTube playing in a slide... and the 10.5 ASK felt ****** to me. How do people enjoy using it? It hurt so bad on my hands to use, and I kept typing on the wrong keys. Who ever created the 10.5 ASK must have been really mad at the world... or just me. The 12.9 is really light as well but awkward to hold up. There's no purpose for using it while holding it up. It's definitely an experience only meant for the desktop or in bed. But I'm so in love with its on-screen keyboard! What a joy! I actually type faster on it than with the 12.9 ASK attached. I could happily use it without purchasing the 12.9 ASK. But I do think it will be difficult to type on the on-screen keyboard in bed as it's better used when laying on a table. However, the ONE important thing than the ASK has an advantage over is selecting all text with the keys. I despise having to hold my finger on the screen for 2 sec to get the "select all" option. Have any of you been in this dilemma up until you actually bought one? I swear that the word "portability" the spun of the devil. It's the only thing that has made me go back and forth because the 12.9 is obviously the real iPad experience.
