Probably a dumb question , but so far, I have held off on the 8.1 Preview for my RT. Just had this feeling that it wasn't quite ready. Thought I'd be better off waiting for the official update. Anyway, it is no around the corner, and I can't wait! But, I have been wondering whether the update will totally wipe the machine, or allow me to keep my apps, settings, etc. Also, have been thinking about whether a clean wipe and update would be better for my RT .... kind of like updating from Win 7 to WInd 8 - I updated one machine, and then later ended up just doing a clean install ..... the clean install was so much better. Haven't seen too much info on this yet. Any advice would be much appreciated.
