Something thats nice is its LTS (long term support) which means it will be supported for 5 years. It works pretty quick as I only have 4GB of RAM. In the past the wireless and video drives could be a hassle. Not this time, it picked everything up out of the box. I didnt do jack.
The only thing I did before I started I shrank the Windows partition. Typical to shrink a Windows partition in Windows is a huge ordeal so I used something called Gparted. I put it on a stick - its Linux with a utility to shrink the partition. The utility supports all these different file systems:
ext2 / ext3 / ext4
fat16 / fat32
hfs / hfs+
reiserfs / reiser4
It took all of 5 minutes to cut my windows partition in half. Than you reboot, Windows runs a check and you are done. Contrast that to Windows itself or any of the utilities you buy. If you do it Windows, windows cries about unmovable files and other crap. Not sure what the big deal is but after I did it, I rebooted it and played with it and it was fine.
Than I installed Ubuntu in the remaining space and used the Logical Volume Manager so I can expand/shrink partitions as I want.
The one thing I can say is its incredibly flexible. Dont like the way it looks? It can be changed to look like Windows or a Mac. The standard interface is very usable and the learning curve is not that steep.
I tried Fedora for a few weeks but the stock Gnome 3 interface drove me crazy. Example it didnt have minimize/maximize buttons by default. So you had to turn them on. I just didnt care for the way it worked. So instead of spending huge amounts of time getting it to work I decided to try Ubuntu. It works GREAT.
You can install software from the command line or through the software store. I already installed some tools to tweak it as I like, Opera and some other things. Opera is very quick as well.
Give it a shot, its a great Windows replacement. I have not used Libre much yet but will let you all know. In the past some of these open sources MS Office replacements were flaky. We shall see. That is a reason I kept my Windows partition. Truth being I dont use MS Office that much at home - about the only thing is to write my resume. I started using Google's spreadsheet for the house so I am off of that too.
My goal is to cut my self loose from Microsofts hang knot (and Apple too for that matter). I think this might be a way to do it. Give it a shot as its free.
