Yes I know about the differences now, also looked a few vids where they've had the 8.1 upgrade. I think the RT would do me fineThe Surface RT might as well not even have a camera its so bad. The Surface 2's camera is great.
Windows 8.1 is on both if you do the updates.
The Surface 2 has a lot better resolution and you notice it. The text is less jaggy and blocky.
The Surface 2 kickstand has 2 positions, the RT has 1.
It doesn't matter to everyone but I used the RT for about a week then took it back to Best Buy. All because of the resolution (and the weight and camera). If those don't matter to you then get the RT. I never had speed problems with it or thought it was slow.
