Downloading Warhammer Beta this weekend

So my boss gave me his spare Open beta key so I'm gonna download the game this weekend since open beta downloads start today. Once the Open beta starts up I'll pop in from time to time. Sadly, (or fortunately) my free time is very limited soooo probably wont really go through and burn myself out on the first 15 or 30 levels before the game even releases. Most likely I'll just get a good taste for the newbie zones and couple of the classes. Should be fun. I'm not delighted that it takes up 15 gb of hard drive.. that tells me its gonna be hard to make space on my laptop (my main development pc), though my desk top had a gazillion of the gigabyte thingies. (Not to mention the download is gonna take a whole day)
