I started with knoppix 3.3 and still using it.

Since we now have a version 3.7, Im wondering if I should change but
Im not sure what the benefits would be since

1) 3.3 have the programs I need
2) Works with my hardware
3) I can actually control it = I have learned some

So what do I get?
Support for chipsets that 3.3 cant use or what is the big difference having a new core?

Will 3.3 stop working on new computers?
