I still use evox as my main dash then xbmc for media.
I've tried to have xbmc as my main dash but I don't like how the 'my programs' is layed out. I could probably config it enough to where I'd like it but ideally I'd want to have 'my apps', 'my emulators' and 'my games' instead of just 'my programs'
also I never figured out how to auto add default.xbe files from any folder/subfolder and have them show up in xbmc. I also don't like having icons for each game, it's just not pretty.
maybe i'm just old-school but for now i'm sticking with evox.
(I haven't even changed my evox skin for a year or more. I have everything just the way I like it for bootup, but i'm always installing the latest xbmc releases, so many new features all the time.)
