Have to say, I'm disappointed. 10536 took over 24 hours to install on my 920. Battery life is completely in the crapper, things seem a bit faster than before, but still nowhere as fast as 8.1. But at least we have universal apps, right? I bought and installed a game on my phone, then went to my PC, and nope. The PC has a separate build of the same game, I have to buy it twice. It's likely an 8.0 game before universal apps, but that's certainly not what user's are going to expect when they buy something in the store and realize it's not for all devices. We were promised a universal store, if that's only going to be true of apps going forward, then it's already missed.
