Thanks Ben.
Could we use something like this with a normal PAYG SIM card in order to connect the iPad to or does the above device use a purely data SIM? We wouldn't need lots of data when we're out and about so don't want to spend £'s every month if we can avoid it.
The grey/black version would be our choice too as it'll probably stay looking nice longer.
As regards memory, there's no way to add to it? No cards, usb sticks or whatever? Why? So when you run put that's it? Seems odd to me.
