That last post (the image and the text above the fold) was posted from within the depths of a MoD establishment via my MobileConnect data card. It’s a very impressive little device which gives me sub-broadband speeds in any area that has a decent 3G signal, and dial-up speeds anywhere else.
In 3G mode I’ve been getting between around 300kbps - with decent latency too - I’ve been able to remote control my home servers quite reliably.
When the signal becomes too weak for 3G it seamlessly fails over to GPRS which is a far more painfull experience! It will revert to 3G as soon as it becomes available again - all without disconnecting the Internet.
Beats sharing a single 128kbps ISDN connection anyway!

So are you proposing to carry on using the MobileConnect card when the MacBook Pro turns up?
