Well, I'll tend to agree more with Kevin's analysis. As graeme pointed out, it's not all perfect tho. Yes, any decent employer will want to interview the prospect in person before anything. But, with the internet, now you can easily apply to many jobs before moving to that new place. There's even some employer that won't take any other form of application. This means that it's easier for the one that will be moving. What I mean is that after you moved, you won't have to start from zero, you might even have some job interviews lined up for you.
For the apartment, or the place to stay, if it doesn't work enough to get you the room, there again, you can at least arrive in town knowing where to go, and what place to see so you don't start from nothing.
