WG - I'm with Orange on their old fiver a month upgrade to the package you're looking at. One or two minor issues over the years but nothing that wasn't solved by a "I want to talk to your retention department" after being put through to mumbai. Very quickly connected with the UK call centre who are more than helpful.
Mrs Target uses the free package in our domestic abode (being a man of travel I have several!) and we've not had any snags with that either over the past couple of years. Both packages are the "up to 8mb" variety but that depends heavily on how far you are from an exchange. "work" abode is out in the sticks a little, but with a low contention ratio so although the line speed is only 3>4 mb I can consistently get that with little/no noticeable slowdown in the evenings. "Domestic" abode is in the centre of a major midlands city and has a line speed of 7>8mb but the contention ratio is through the roof, so download speeds are fantastic at around 2am but pretty poor 5pm>9pm when the world and his dog are watching Iplayer
Overall, I've been with orange BB for a couple of years, had one or 2 issues but generally excellent serivce.
On the mobile front, Orange Mobile retention department is absolutely fantastic. They couldn't have been better when it came to contract renewal time, and gave me a package so good that I even had the guy who rang me recently to check how my new phone was doing asking how I'd managed to get a better deal than his employee discount rate.
