Over the last few weeks I have been lazy and distracted from doing actual work (as in something that pays) in the evenings. Thats why I have been doing searches like Top 10 Ubuntu applications.
Some of what I have installed and started using (not in any particular order):
Katapult (sudo apt-get install katapult)
Application launcher that matches the application name as soon as you start typing the first few letters. Launch it using Alt-Space.
Kopete (sudo apt-get install kopete)
Enhanced multi-protocol chat client, webcam and voice(?). Like the interface on first impressions, but it will take a lot more to move away from Pidgin.
GParted (sudo apt-get install gparted)
Gnome Partition Editor, utility for disk partitions that reformats hard drives into many formats including FAT16, FAT32 and NTFS. Will need to try it out soon since I am running out of disk space in my Ubuntu partition if I keep installing applications at this rate!
Some that I have installed and then un-installed (of course in that order):
Tried it as an enhanced chat client that does webcam and voice, but the interface is crappy at best.
Some that I would soon try (probably in that particular order)
music player with last.fm plugin and some other features (I will find out).
Desktop RSS feed reader (sudo apt-get install liferea)
