Re: Upgrade to a more useful, sexier, *real* operating system. Linux
"but everyone who believes that it will come without major issues will be disappointed."
I have used SUSE & OpenSUSE since the late 90's - I've NEVER had major issues.
I currently run OpenSUSE 11.4 on my low-powered, file/print/odds&sods dual core ATOM server, laptop, netbook and dual-core Intel at our holiday home. I run 12.2 on my two work stations ( AMD single & dual cores.) I've almost always used KDE.
I have no problems with graphics including hardware accelerated 1080p/50 video, 3G dongles, serial/USB converters, scanner/printer & printer. I can process RAW DSLR files at 16bits/colour, video edit 1080p/50 video and heaps more. I use SSH to my file server for proxy access to iPlayer, etc whilst I'm away. Skype, GoogleEarth all fine.
I do use Libre Office which I find sufficient for my needs - big spreadsheets are slower than Excel but otherwise....
On the other hand I've got a great selection of programming languages , of which I regularly use C and tcl/tk & shell scripts.
I don't recognize this picture you paint
