Not sure if this has been discussed (or is already possible) but I would like to have MicroB direct me to mobile versions of websites when on 2g. The desktop versions of websites work great on 3g/wifi but I find 2g to be insufferably slow.
Maybe this could be an enhancement to the user agent switcher plugin?
EDIT: The proposal is to make this a user option, so if you are happy with the desktop versions of some sites at 2g speed you can turn it off.
