During my school and college days i had a linux fascination but later i realized it will always be
1. My second choice OS during dual boot.
2. I will open it only once a week.
3. I will use it only to play songs and the inbuilt games, which is better than windows games.
4. Will browse internet through firefox and think in mind how secure i am.
5. Recover data if windows get infected.
If I ever have very urgent work to do, then I'll boot Ubuntu. Especially when its related to internet. Even though Windows takes just around 1 minute to load, it looks like ages to me, when compared to Ubuntu's boot time.
