i have purchased a Dell mini direct from dell (got it cheap through my account manager) and i'm just hunting for a way to use internal 3g now, possibly dissect my vodafone USB modem and find a way of mounting it.
I confirm the slot is empty, and useless, as there are no ariels or card slots for the actualy 3g hardware, the vodafone model includes these but for £25 a month for 24 months, itsa rip off.
