I've given up. I got rid of my Surface RT and switched to a Samsung ATIV.
Reasons:
Apps for RT - this just isn't moving fast enough. The market is also poorly curated. New apps DO come out, but the "just released" section is never updated. Apps I'm missing most are Spotify, Google Drive and a GOOD media player. The built in one SUCKS and has limited support (just like an xbox). There are others, but they are quite weak, and none have DLNA support.
Keyboard issues - I've suffered from random keyboard issues. Sometimes it just doesn't connect, requiring a reboot.
Storage space - This was a big one - even with the couple of apps I downloaded, I only had room for about 9GB of movies and music.
I *LOVED* the hardware, but I just can't deal with the apps issue. Perhaps when Surface pro comes out, I'll switch, but so far the ATIV is quite lovely.
