I have been using my 64gb surface for two weeks now. Took it to the lions den(where MacBook air/pro) on the day after I bought it, and actually was not afraid. Some of them came over and ask me to show them the features. Some told me that they will be getting them for Xmas. Today I came back to the den, and saw 3 other Surface users are there proudly using their new toy.
FYI. You CAN lock the rotation screen to either landscape or portrait. Once you decided to go landscape or portrait, activate the charms. Click settings, then click on screen and activate the lock screen icon. This will stop the screen rotation to your desire(portrait or landscape).
