The phone is free, tied into a 2 year contract! so, in the end, £13 x 24 and the phone is mine to own. It's technically a £150 phone so paying £312 over 2 years isn't that bad really. 3 network only just recently put that 1 gig allowance on the internet data after they took on so many people they realised their network would struggle.
The E63 is a bit slower over the 3G network than the E71, but it's not disastrous. The E71 is thinner and a nice metal casing, but the E63 fits my hand and has a more mature keypad that doesn't bug me as much. And for BBC iplayer users, there is a way to clone certificates for the E63 (why has the BBC not whitelisted the E63 is a large debate amongst users) although I've not personally tried that yet. Oh, and a 3.5mm headphone jack on the E63 whereas the E71 is 2.5mm.....
I had the official £50 keyboard for the PPC. It was slightly smaller than a full size keyboard, your fingers would brush up against each other and accurate typing speeds were down, but the keys pressed down pretty well and it didn't break in several years of using it. I managed to get another plugged-in, transformer like collapsing metal keyboard for my dads more modern PPC. They are not as bad as you think

Just expensive, compared to the cheap ones I use for PC's that I hammer away on.
