I just started to use Linux again after several years of being stuck with Microsoft. I figured out that maybe I'll just install some good counterparts of the software that I'm using with Windows 7. I would like to ask you guys about your opinion as to wich are the best alternatives for the following popular windows software: 3D Studio Max Adobe After Effects Adobe Photoshop Adobe Lightroom Adobe Dreamweaver AutoCAD Google SketchUp Microsoft Office Nero Burning Rom Picasa Quickbooks Sony Vegas Pro Staad Pro Windows Movie Maker I'm using Kubuntu Linux by the way and it would be great if they can run smoothly in Kubuntu. I also prefer programs which are free and under GPL. You can post alternatives of softwares that are not included in the list as long as they are popular and are commonly used programs. Thanks in advance!
