Photoshop alternatives
Photoshop has more than one alternative GIMP and Paint.NET
GIMP
A graphic editor wich does not look like Photoshop and UI just sucks.
GimPhoto
That's more like it :p
PAINT.net
Illustrator alternative
Inkscape
Flash
Synfig
Dreamweaver alternative
KompoZer
After Effectss alternative
Jashaka
UI seems like as hard as the name itself ( Jahsjaka, ja shaka, jas haka?)
Haha! Take that Adobe! They are going bankrupt in no time! Now let's take down some other companies too.
3ds max alternative
gmax
Ofcourse Blender is seen as world's best free 3d modeler but it doesn't even comes near to how 3ds max looks like. So if you want it to look like 3ds max you should try gmax, howhever it's more for creating game models.
Fl Studio alternative
Linux MultiMedia Studio
Fl studio is probably one of the cheaper audio softwares around but still quite a lot. So there's an alternative Linux MultiMedia Studio, and guess what! It's also availble for windows!
