step3 - media players, utility apps, clamtk, rootkit hunter, hosts, wine

Media players and desktop apps 

first update the package lists with
sudo apt-get update

or, if  you update the list more than once a day, you can use 
sudo apt-get update -o Acquire::Pdiffs=true
which dowwnloads only the differences in packages lists, and can save you time - but it will take longer than a normal update if you haven't updated for a few days.

In KDE's control panel you can set the appearance and colors of all KDE apps which is handy.

Wine is a platform for installing Windows applications on Linux. It doesn't hurt anything to install it and it works quite well (except for glitches in the apps themselves), and is indeed very useful if you really need a Windows app working. But it's quite a lot of disk space, some 400Mb installed? 
I've found out that I can do what I need to do without it -that's image editing and uploading. Digikam says it all really -even though it needs some better features.  Picasa demanded quite a sizable disk space allowance for my 70,000 pics, some 12Gb for its db3 cache on my box. Also, Google aren't continuing support for it on Linux.  So it's time to get off it and get on with using what alternative apps Linux has for image processing. See my Image processing page.

first enable multiarch (as per Google earth install, step2), then
sudo apt-get install wine:i386
check the latest version

Step 4 - CD ripper, audio editor, Chromium, Opera, Bible, GPS setup, Viking, Skype
