I would expect the beta to last a little longer then a few days before giving up on it. However, they should stop the forced redirects. Those who want to shape it for a few more months can help mold it before another test.
My issue with the beta is that when I re-size my window 860x1080 1/2 Screen Width the entire UI goes away. While this is great for browsing comments its horrible for browsing the main page as it takes away all of the configuration options. I'm assuming that this alternate view is some sort of mobile solution, but that is a fairly big solution.
Personally, I never browse the web at full screen almost all web pages look better at around 1000px wide and I can generally side scroll to ignore address if I run at half of 1920. I think any modern UI design should consider what windows thinks of as dual page mode. Why waste all that real estate. I'm likely doing something besides browsing the web.
