Yeah, there's not really much point in bringing the internet stuff. They send it to you, like GibbyGab said, plus you might not have the same kind of connection that you have in the US. It's really easy to get it all going as well, at least with a MacBook.
The only reason it seems to take so long (from what I can tell) is that they're terrible at planning. Some companies tell you that you can't call to set up until a week/2 weeks before you move and then when you call they can't set you up for another 2 or 3 weeks because they're booked up.
Why don't you just let me call when I know I'm moving and we can have a better date set up ahead of time?! They wouldn't have to change a single thing about their process, and people would be happy for being able to set up an appointment well in advance and would think it's great customer service for not having to wait ages. I don't get it.
That said, like GibbyGab, the longest I've had to wait is about 2 weeks. I just got myself a library card and went to the library if I needed to check my e-mail or anything.
