- Mozilla Firefox and Opera Browser: Mozilla Firefox is the default browser for Ubuntu users. No doubt it is the best browser in the world, and with amazing list of add-ons it just becomes irreplaceable. Even then I would recommend you to give Opera browser a try. I have found Opera being faster than Firefox sometimes. Download and install Opera from here.
- WINE: Sometimes people refer WINE as a Windows Emulator but it is not an emulator. In official terms, Wine is translation layer which is capable of running Windows applications. Though not all applications can be installed using WINE, yet it is the best choice for some Windows only software to run under Ubuntu. Learn more about WINE at http://www.windhq.com.
- Virtual Box: Virtual Box is a must for those who want to get the best from both the worlds. It is an application which magically lets you run another/multiple operating systems within an operating system (OS). So you can try various other OS like Kubuntu, OpenSUSE, Fedora etc and even Windows and Mac without having a need to reinstall your existing OS. How cool is that?
Besides using VirtualBox (VB) to try various other OS, you can use VB to install software which have no Linux alternative like Windows Live Writer etc. Best thing about VB is that you can use both OS (host and guest) simultaneously.
The instructions to install VirtualBox are mentioned here. However it is as simple as downloading a .deb file and running it. To see how you can run Windows 7 within Ubuntu, check out this earlier article on Knowliz.
- Thunderbird or Evolution: In fact the use of desktop email applications is reducing everyday. But if you are still a fan of desktop email application like Microsoft Outlook, then Thunderbird is definitely the best choice for Linux users. However Evolution is the default email client for Ubuntu which seemlessly works with other Ubuntu plug-ins. Everyone has his own opinion about these two apps, so no single app is a winner.
Don't forget to use Lightning add-on for Thunderbird.
In fact a third appliation Zimbra, a Yahoo company, is also used. All of these applications support multiple POP and IMAP accounts.
- OpenOffice.org: OpenOffice is the Linux alternative for Microsoft Office on Windows. OOo comes as the default Office application on Linux. It is very powerful office suite which includes Word (Word Processor), Excel (Spreadsheet), Presentation, Drawing, Database and other applications. Other than that you can install add-ons too to make it even more powerful.
(Don't forget that you can use it for FREE on Windows too as a replacement for costly MS Office.)
- Project Management: Search and install 'Project Management' from Synaptic and along with OpenOffice.org mentioned above you have a complete Office suite including Project for managing your project milestones.
- Music Players: Rhythmbox is the default music player for Ubuntu, but I prefer using Songbird and VLC player. Both of these player players play most of the audio and video formats but based on your preference you may chose one over the other. But all of these are really good music players.
Find out how to install Songbird on Ubuntu.
- Boxee: Boxee is like Windows Media Center and even better. Boxee can pull in feeds from various web apps like Pandora, Digg, Youtube etc and play within the application. You can install various Boxee apps and use them to quickly go through the content of that feed like Last.fm, Fashion TV etc. or you can add your own feed URL to view within Boxee.
Boxee is still in alpha, so sometimes it does crash, but overall I am happy using it. Can you believe that you can control Boxee from your iPhone using Boxee iPhone app. I will strongly recommend you give it a try. You can get Boxee from here.
