I'm thinking of replacing my Surface RT with the Lumia 1520 that I just purchased. Virtually every app I use on Windows RT has an equivalent Windows Phone 8 version, and there's even an app for RDC and RemoteApp connections. With an Amazon Instant Video app supposedly in the works, there seems to be little reason to hang onto the RT. I just don't know what the market will take for a Surface RT these day, or if it's even worth trying to sell.
