Steam accepts bitcoin.

Quite a few domain/web hosting/VPS companies accept it, like Namecheap and Namesilo.

Online gambling sites accept it for obvious reasons.

It's hardly ubiquitous, but for some things it's fairly practical.

Many vendors (including Amazon & Walmart) indirectly accept bitcoin via gift cards (Gyft, cardcash.com, etc).
