Is 128gb enough for me?

Hey guys, just wondering if you guys think 128gb ssd is enough for me.

I am going to install windows via Bootcamp, but i won't really do anything with my MacBook (Air), except for basic web surfing or writing emails.

I'll mostly store all my documents on my desktop, and i delete all the movies after i watched them. No photos at all, and not a lot of songs.

The programs i will install are windows(on windows portion), fifa 13 (14), itunes and other basic programs. I am planning to install windows home premium, because i heard that had the lowest amount of gb.

Anyways, do you think 128gb is enough? And for anybody who installed windows with 128gb, are you experiencing any trouble?

Thanks!
