Storm, you're very lucky there.
The 3G Broadband coverage here in the UK has been causing some disquiet from the users - who are few and far between, but are steadily growing. I can't get any connectivity at my home and at the office I get "G" rather than "3G". Connection speeds are about the same as dial-up. It's fine for general web browsing and Email (when the Orange UK mail servers feel like it), but any downloads over a couple of Mb are just too slow. RB functions OK with Network data download and sharing, but if the connection glitches, I do have problems.
In areas where there is good 3G network coverage, users are complaining that the speed is inconsistent - a bandwidth problem I'd guess.
Orange UK call the 3G connection "Internet Everywhere" - a bit optimistic I'd say. I have a 3Gb monthly data limit - that's upload and download combined. However, even leaving the connection on for 8 hours a day, the most I've managed to use in a month is 422Mb!
OK, so it's considerably better than nothing, especially as I'm going to be on the road for a couple of years and I don't want to be tied to a land-line Internet provider whilst I'm away. I'm hoping that the system will mature and things will get better!
