I mainly use my phone to go on CS, which means I see the mobile version, and it definitely makes the site easier to navigate but there's a few features it lacks that make me have to go back to full view every now and then.
First and foremost the lack of a search box in the forums.
Every time I go to look for something specific, I go up to use the search box but forget its not there, so I have to go down and switch to full view which takes me back to the front page, so I have to go back to where I was in the forum, use the search, then go back to mobile which takes me back to the front page again, It gets pretty tedious.
I get that when you switch back and forth between full and mobile it needs to reset the website so you end up on the front page, I'm just wondering if they could possibly add the search box to the mobile version as well.
One other thing that is a little disappointing, is that the mobile version doesn't change backgrounds with the holidays. Not a big deal, but would definitely make the mobile version more fun.
