The major reason that people don't use Linux as a file system is twofold.

1. Compatibility with hardware... this has been for the most part resolved. Just about any hardware you have that is for Windows will work fine with Linux (MAYBE with a little work).

2. Games. I am kind of surprised here other than the fact that game designers don't see the profitability in porting their games to Linux. With that said... OpenGL has been around for quite some time (at least 10 years) and writing in a language like Python with PyGame, Panda3D, as well as other plugins can make some pretty kick-ass 3D games. One of the most famous games I know of is Frets on Fire which is written for Windows/OSX/Linux all the way back in 2008!

Come on game developers... the more software we can get into the Linux community the more people who will port to Linux (especially from WinDOZE).

Call me a heretic, but there are times that LibreOffice documents and MS Word documents just don't quite mesh. So, I'd like to see MS Office ported to Linux. In addition to that, I'd like to see Quicken and tax preparation software, such as HR Block or Turbo Tax.
I have been able to get MS Office 2010 and Quicken 2009 to run pretty well with CrossOver. I have yet to get H&R Block or TurboTax either one to even install, let alone run on CrossOver. Crossover, as most folks know, is the commercially prepared version of Wine, and well worth the $39 (US).
As far as paying for any of these programs to be ported to Linux, I'm thinking maybe $25 for tax prep software, and $75 for MS Office.

If the university requires it you have no choice, but why would they not go for R?

In particular, OTSAVDJ and OTS Radio Webcaster. They are only available on Windows at present.

Two programs I would like to see in Linux are
1) DeltaCAD 2 dimension drafting and
2) IrfanView Very easy to use draw and photo editing

Affinity's software, a photoshop and an illustrator like program, rivals Adobe (may be better). Commercial software that I would buy for use on my Linux machines.

Scrivener. This writer's software is already available for download free in beta form. It works OK but needs a lot more work. (see: http://scienceblogs.com/gregladen/20...youll-like-it/ ). It would be great to have a fully functioning supported version. Again, this would be commercial but worth it.

I would like to see Linux get newer and better super-duper GUI file management software. There seems to have been a partial de-evolution in this area. The Mac has a great finder replacement called Path Finder. It has all sort of bells and whistles. I would love to see a version of that made available for LInux.

Netflix in a form that does not require all the messing around one seems to need to do to make it work.

iTunes. This is a major piece of software we need for Linux, since a lot of people have iPhones.

Netflix can play natively on Linux using Google Chrome. Last winter I was watching my Netflix on Linux with no issues.

QuickBooks.

Photoshop And Premier Pro

It already exists, but I would like the bugs ironed out on f.lux, for it to be on-par with the Windows and smartphone versions.

TurboTax, iTunes (never gonna happen), Google Drive,

And a 2d (hand drawn) animation program. I have tried Pencil2d, but development doesn't have enough resources. It's unusuably buggy, alpha software, at best. So I guess pouring some resources into this project is my real request.

Linux-native Quicken. Linux-native Dragonware Naturally Speaking. Linux-native Apple iTunes. Linux-native MS Outlook. Yes, everyone, I know about Wine. Have used it occasionally successfully. I would like native-Linux versions.

I'll second tax prep software as a suggestion. At least one major company, that I use, is entirely web based, but accounting plus tax would be good on board. (Wasn't there once a "Linux Money" program back in the old days?)

Definitely the Adobe Suite.
If I had to choose, in order of preference, Photoshop, Indesign, Illustrator.

Oh, and Microsoft Office (Word & Excel)... Sorry about it, but it's still a leader in the private sector, and it's often a deal breaker when I offer to install Linux instead of Windows on clients and friends computers.

As up to now no single graphic design tool ever came close (no Inkscape does not), CorelDRAW is dearly missed.

And the *all* vendors of update programs for device (GPS, mobile phone, printer) software (Garmin, Nokia, HTC, …) should have Linux versions of those

The user interface is so efficient. Batch operations so useful.
