- AutoCAD/3D modeling equivalents: there are already two very good native CAD programs, BricsCAD and DraftSight. The first is closed-source and commercial but very very similar to AutoCAD, and the second is also closed-source but free and it's a little bit different from AutoCAD. Blender is absolutely brilliant, but it's not 3DS Max so it will require learning something new if the expectation is that it is 3DS Max. Also I suppose no one is born knowing how to use 3DS so there was a learning process in there as well.
- Android is not Linux: Doh! Of course it isn't. Something like "Android is not Ubuntu" might be more appropriate, since Linux is only the kernel that sits in the middle of both Operating Systems.
- It is perfectly possible to do serious graphic/photographic work on linux-based distros. I have been doing that for the past year perfectly fine.
- The No Games part really cracks me up That whole paragraph seems to really be "Big companies don't port their latest titles to Linux, and I don't consider games older than 5 years as real games. Oh yeah, and I only consider something to be a game if it runs with wine, so all the native indie titles out there aren't games."
- I won't bother commenting the "General Linux problems" because it has so many incorrect and false statements that it would take me a while.
BTW, that page says it's not a Linux vs. Windows page, but in reality a lot of issues raised there are "Windows does this, Linux doesn't", like inability to run windows programs in linux... I can also come up with a list of programs that run in linux-based distros but not on windows :P The conclusion from reading that page is that whoever wrote it expects Linux-based distros to be just like Windows, and since they aren't he complaints mostly about the differences.
