Have u upgraded to Mavericks?

You can upgrade directly to Mavericks (which is free) provided your Mac meets the requirements, which are:

• OS X v10.6.8 or later
• 2GB of memory
• 8GB of available space

and the supported models are:

• iMac (Mid 2007 or newer)
• MacBook (Late 2008 Aluminum, or Early 2009 or newer)
• MacBook Pro (Mid/Late 2007 or newer)
• Xserve (Early 2009)
• MacBook Air (Late 2008 or newer)
• Mac mini (Early 2009 or newer)
• Mac Pro (Early 2008 or newer)

It is available from the Mac App Store (in Applications) (it will check whether your Mac is compatible and won't let you download it if it's not).

You should be aware that PPC programs (such as AppleWorks) will not run on Lion or above; and some other applications may not be compatible - there is a useful compatibility checklist at http://roaringapps.com/apps:table

I was going to update to Mavericks, though after reading all the problems other Mac users are having I cancelled the download..!! I am currently running OS X 10.6.8 which is working fine..!!

If you are using Serato or Traktor you should plan your upgrades accordingly

Updating to any system later than 10.6.8, there is no more Rosetta. This is significant as it leaves a whole bunch of applications out in the cold, as this tip explains:

https://discussions.apple.com/docs/DOC-6271

Backup your data, and plan your application and driver updates accordingly.

I did and reverted back to SL (period.)

... is there an easy way to get rid of all the PPC apps successfully?

In many cases you can just delete them, though the prefs files will remain (but these are very small and in any case you can delete them). There may be additional files in (user)/Library/Application Support which again you can delete. Some will provide an uninstaller (often as part of the installed) and it's worth using that.
