10 things a Mac/Pc does better than Linux, and which are deal breakers for me:

2. Adobe Illustrator
3. Adobe After Effects
4. Adobe Premier/Apple Finalcut pro
5. Autodesk 3D Studio Max
6. Adobe Dreamweaver
7. Adobe Director
8. Adobe Flash
9. Adobe Indesign
10. Games
Seems all that is holding you back really are 2 things. Adobe and Games.
In time Adobe will come around.. I hope.
