Things I miss in Windows

foobar2000: none of linux apps at present can compete with foobar2000 in my opinion. it's super lightweight and fast with very huge set of features like extremely-fast playlist managment/search, better support of non-ascii characters in id3 tags, variety of input plugins covering all music formats I have like mp3, wma, ape. You can have almost all features by installing plugins...just like firefox.

minilyrics: when I play, it can automatically display the lyrics! if it's not available locally, it will download from the internet in a second.

(thinking of any others...)
