When switching to Linux, the first thing you need to understand is that Linux is not Windows. Sure, Linux is more stable and secure than Windows. and Linux runs faster than Windows. This is because Linux isn't bogged down with a lot of software running in the background (anti-virus, pop-up blockers, etc.) on the lookout for a possible virus or Trojan infecting the system. Linux is immune to Windows viruses.
But Linux is set up to run Linux software, not Windows software. So if you're using, say, a desktop publishing application in Windows, you're going to have to abandon it for a Linux alternative.
Luckily, Linux has thousands of software programs available and many are top notch! In many cases the Linux alternative is better than the Windows program you're currently using.
A great place to see which Linux program will replace your current Windows programs is Linux App Finder.
Linux App Finder lists Windows programs in the left hand column. In the right hand column, it lists those Linux applications that will replace the Windows program. In many listings there are several Linux apps to choose from. So, if one doesn't quite feel right or give you the desired result, simply move on down the list to the next offering.
The only other thing you should be aware of when moving to Linux software is relearning some"moves" in the app's interface. Just stick with it. You'll find it'll become as easy and familiar as that program you were using in Windows.
And yes, if there is that one Windows app you really need, there are ways to get it to run in Linux.
But take that first step. Get Linux. Or get a Linux computer. There are thousands of Linux software programs waiting for you. It's a fun computing adventure!
