Hi,
So this is the thread where I list some of the things that make me prefer Windows (7) over Ubuntu, and you convince me that Ubuntu is actually better / share thoughts / etc, and make me want to stop using Windows as my main OS and switch to Ubuntu right away.
1. Gaming
-Some of the games I play the most are Oblivion, Fallout 3, Bad Company 2, Counter-Strike: Source, Half-Life 2, and Portal

. It seems that it is possible to get Steam running on Ubuntu, but I was wondering if any of you who play similar games on Ubuntu under Wine could share how much of a hassle it was to setup, how it performs, etc.
2. Programming
-I love the .NET framework. It's easy to use, fast to develop with, has the WinForms designer, .NET Reflector

, the Parallel library, LINQ, etc. All the programming courses I have taken were in Java/C++, but I learned C# on my own, and it just seems much easier/faster to use than Java, and seems to have more useful features
-XNA Game Studio for faster game dev on Windows, Xbox360, and soon, Windows Phone (also, some of my classes require this)
-Visual Studio (2010). VS2010 may take up 4x as much memory as VS2008 since it uses WPF/has more features/etc, but Eclipse takes up 4x as much memory as VS2010

! VS also seems easier to use, but maybe that's because I use it more.
-DirectX (also, PIX debugger). It irks me that OpenGL has no built-in functionality for vector/matrix/quaternion/etc math, loading images, loading models, and that I need to go and find libraries to do so. Also, the extension system irks me too. Both DirectX and OpenGL are used in my classes, though. (Random: Anyone know of a nice list of deprecated OpenGL features?)
-Not much that can be done about this, but at my job, C# and C++ are the languages that most of the programming is done with. Most of the website tools are also done with ASP .NET. There are two JSP tools, but they are really slow and awkward to use. (Though maybe that is because the developer didn't know what they were doing?)
3. Other
-Maybe this is just me, but Ubuntu seems to have graphical / ui glitches on my machine. This is especially true when Ubuntu is starting up. At least this version doesn't have weird artifacts whenever I open a window, but it does occasionally position items in the notification area on top of each other.
-Office. Everyone else uses Microsoft Office, and iirc, OpenOffice does not always correctly display MSO formats. I don't know too much about how the features compare, though.
-I love the WinKey+Up/Down/Left/Right keys for quick docking of windows. Also, the windows restore to the original size after undocking them.
-I've had issues in the past where if I spam the refresh desktop key (because I feel like it), it seems to get stuck generating the PDF thumbnails for forever.
I forgot a few, but perhaps this is a good start?
Thank you.
