answer:Well, actually it depends on how do you use your PC, but generally I would have to say that it really is: a good Linux distribution (such as Ubuntu, Fedora or SUSE) can be an excellent choice compared to any Windows version. I couldn’t say the same for Mac OS X (which, by the way, it’s actually a remote UNIX relative) because I’ve never really used it. Linux it’s way more secure than Windows and usually the communities that develop around certain distributions are helpful, educated and savvy. If you choose a Debian-based distribution (such as Ubuntu) I can guarantee that you will love Synaptic, a “package manager” that actually is a huge repository of free software: you just search for what you want to install, and Synaptic (or apt-get if you prefer the terminal) will download, configure and install it, as well as always keeping it up to date. There are Free Software alternatives that work on Linux for practically every software you may need, and since there are many governments switching to Linux/Free Software/Open Source, you may expect that their development will only lead to an increasingly better software. Also, there is ****, a compatibility layer that allows to run Windows programs on Linux, and, as a last alternative, you could even set up a virtual machine to run essential software that’s not available for Linux. Oh! And I almost forgot: Compiz Fusion! It has some really cool effects, sure, but that’s not all. Once you start using it, you’ll see that you’ll certainly be more productive.
