I now am able to reieve Broadband!! I know - probably the only person ever not to be able to have got it already!

Question is, which would be a good ISP to go with

So many choices, but don't know enough about them to make the choice, so though I'd ask here

I'd also like to know how you would be able to share the internet connection with another computer - namely a laptop

I have my own Desktop PC and Dad has a Laptop, I presume we would both need to be with the same ISP (if so, how does emails etc work?), but how would we go about connection (is wireless possible??)
