I have done a hd-install of Knoppix v3.4 and everything is working just fine (in fact just perfectly), and I was wondering whether I should do an apt-get update periodically to keep things upto date.

Since v3.4 is based upon Sid, which is unstable, isn't it potentially very dangerous to update (being a beginner)?

After all, if it isn't broke, why try to fix it?

What are the advantages/disadvantages of updating periodically?

Thanks
