There's no personal photo management and editing software for Linux? I guess I better tell the developers of F-Spot, Shotwell, and Darktable (and perhaps a few other projects too) that they don't exist. I personally use Shotwell; I used F-Spot for awhile, but older versions of F-Spot had show-stopping bugs for me. Shotwell has transparent RAW conversion and a few basic editing options. It's easy to open photos in a "real" editor (eg, Raw Studio or GIMP) for more extensive work, but for many photos it's sufficient.
Likewise with video editing software. Lately I haven't had much need to edit videos (other than transcoding or basic effects, which is easily done with ffmpeg or mencoder), but I know that video editing software does exist for Linux. Kdenlive is one that I've used most recently. It's not bad. Then there's Cinelerra, which is supposed to be the most advanced NL video editor available for Linux. I used it once in the past, but it was sluggish on my antiquated hardware at the time. I know there's a few other NL video editors out there for Linux, but I can't recall their names at the moment.
For vector graphics, there's Inkscape.
For that legacy in-house Windows-only software for which you lost the source (shame on you for losing it in the first place!), there's Wine. But frankly, if you lose internal source code that easily, good luck keeping track of all those software licenses!
At work, I use VS2010 Express for one of my projects, and if the full version is anything like it, I say "no thanks". It's buggy (especially the Intellisense, which is more like Nonsense sometimes), and the editor itself is nothing to write home about. I also use Netbeans for both Java (a fairly large Java project at that) and C++, and it's a far better IDE. But for this one project I have to use some Microsoft header files which don't work with GCC (some of their headers have syntax errors!), which is why I use VS2010 Express. Of course, I could probably use the VC dev tools in Netbeans, but that just seems wrong for some reason.
So really, it seems like you've been living under a rock (or under Microsoft's shadow, which is roughly equivalent) for several years when it comes to Linux. Either that, or you're a troll. Take your pick.
