File size is only about 1 GB too. Even if you're only downloading at 500 KB/sec it only takes less than an hour to download it. Go watch TV or grab a snack or something. It'll be done when you get back.
And if you're not downloading at at least 500 KB/sec, you might not be getting the most out of your connection somehow. I got a cheap 5mbps connection and I easily go at 525 KB/sec, which is my maximum speed, from Nexus on a free account. The only times I don't get that much is during western hemisphere peak hours, where it can drop down a bit. I have a lot of friends there who get way more than that with their faster connections on a free account too.
If you have a really slow connection just leave it downloading overnight or something.
