Multiple users on Jelly Bean 4.2 - experience or reviews

Hi all,

One of the biggest draws for me regarding the Nexus 10 has been the possibility of having multiple user accounts for the tablet, so that I can just get one that can be shared between my wife and I.

Does anyone have any first hand experience on how well this works, or know of any reviews where it is looked into in any detail? For me this is a great and pertinent feature, but many of the reviews seem to gloss over it.
