I often do this, and I'm an experienced user. I know exactly where the address bar is and what it does.

If you were paying by the minute for your ISDN again, would you rather take 10 additional seconds to load Google and click the appropriate link, or would you prefer to take an extra minute or two to figure out that they sprung for www.store-name-us.com rather than www.storename.com? Most large sites will have all the common variations redirect to the correct URL, but it's pretty easy to run into a situation where googling is faster and easier than trying to figure out what domain they decided to pick.

You're twisting the meaning of DRM to make a business model you don't like look bad. There are valid reasons for disliking Blizzard, or WoW, or even any pay per month MMO, but DRM isn't one of them in this case.

If you want to get into technicalities, DRM is Digital Rights Management. I don't think the EULA qualifies as a digital restriction.
