The app argument is overrated. The real problem is games. People want to play Candy Crush, Despicable Me, Plants vs Zombies 2, other games not in the Windows Store. Productivity wise, W8/RT have superior software, and both have a browser with full adobe flash which means if you wanted you could use all of Google Services aside from the Chrome Store. Multimedia wise Windows has all the important radio, video streaming services such as TuneIn, iHeart, Slacker, Amazon Video, Pandora etc etc. I'm not sure what else one would want. I have a Note 3 (lovely device BTW) and have a ton of Android games but I don't play most of them. What MS really needs to start doing is leveraging their Xbox Platform. They need to have some incentive (if they don't already) to either port their game to the Windows Store or build a mobile version that can be used on W8/RT/WP8. Might also help if they had some support from Valve's Steam Platform, but the problem with that is Steam is only x86 and not available on ARM.
