i'm all for advertising your brand, etc. but when it impacts my ability to use an application/website, it makes me mad.
take msnbc mobile for example...50 vertical pixels wasted:

a huge banner ad for windows mobile. here's my questions:
- shouldn't the site know i'm already using windows mobile?
- shouldn't it know my device capabilities and realize that they just wasted my screen space
- what would msnbc publishers think that i can't even see the top headline...
this site has turned from a news site to a banner ad...hey anyone on msnbc listening?
