Quick Steam question

[Lethagized]

I'm on a 3G connection at the moment until the 9th september. I want to buy Deus Ex HR but obviously can't download the game on 3G, so can i log in to my steam on my dads pc at his house, download the game, back the games onto disc, then copy the files onto my pc?

Thanks fellas. I actually did it similar to method 2, but i verified the integrity of the files which sorted it all out and now it's all working sweet.
