So the best way is to do the same which I did years ago.
I installed Ubuntu on second partition, without removing Windows.
I was browsing Net through Ubuntu, watching movies, listening music, all day-to-day stuff.
On Windows I was only playing games (it was time when I was not working using computer).
After about 3-4 months I didn't even realized that I stopped using Windows completely

You can try this way.
About software it's no problem. On Linux there are lot of nice software for day to day use. I bet that all of your favourite software have their replacements on Linux.
The rest of software you can run under Wine/VM.
I know this will hard at beginning.
Every bigger change in life (such as changing OS

) is hard, but with time you starting to see that you made good move and everything is now better than in past.
