It is, but....that's not saying much. I loved the 920, it worked great for me for 2yrs, then I downloaded 8.1 and it became useless - no camera, randomly called people, wouldn't pair with my car, <1 day battery life. I got the 1520 as a replacement under insurance, and was unsure about the size. Reviews were glowing so I accepted it, and it is a spectacular device - beautiful, great screen, fast, smooth, excellent camera - all is good, right? Unfortunately no, the size is wrong for me. Uncomfortable in jeans front pockets, and worse, I think the size contributes to it's fragility. I dropped it one time, from 4 inches, and the screen cracked. So many people have the same story - it's just not at all durable. I know one other person who has one - cracked screen first week. It's not a good daily driver phone for me. Too big and too fragile for a $600+ device. Now it constantly pulls up Bing Search, hops from one function to another, freezes. It's just a little crack in the corner, and one across the face, but it's screwing up the phone. I laid a piece of tempered glass across it to hold everything together for now.
But what are the alternatives? The 1020 looks like it'll work, but it's really no upgrade on the 920 - 400 series Snapdragon processer, etc. Camera is nice, but real world does it take better snaps at, say a concert at night, than a high end Android or iphone? Big drawback to 1020 is no Qi charging, (I'm on ATT).
I'm likely going to pick up a used 920 on ebay while I wait for a better WP to come along. I want the durability and Qi charging of the 920, the processor, battery life, micro SD slot, RAM and camera of the 1520, with a 5-5.3" screen.
As for games/apps, you can install at SD. Just go to settings and choose SD as the location for installing new apps. You can move also your existing apps from phone to SD by tapping the phone memory and choose the app/s you want to move.
