I am ready to pay for quality products that I use. A hardware
multitrack audio recorder used to cost thousands of dollars. Those
softwares can do a lot more, video and audio editing and
synchronizing, DVD authoring for less than $1000, it's a pretty good
deal.
Take a look at Native-Instruments Komplete 7 bundle at $600 and try to
imagine how much would cost all the included instruments in hardware,
more than a few hundred thousands. Tell me there's an equivalent in
Linux and that I've been ripped off.
I thought I would be getting a bunch of suggestions for "great" Linux
open source softwares to replace those, doesn't look good so far!
You will not find many equivalents of large commercial one-off packages
available for linux, nor should you expect to. Consider the thousands and
thousands of hours of development time it takes to make such packages - who
would waste their time making an open source equivalent for something like
this that has such a small audience?
Office packages? Sure. Open Office has become quite mature, and if you want
basic home/school/office/internet/etc., Linux works great. If you want to
explore how an operating system works by investigating and coding in cpu
schedulers, i/o schedulers, memory management algorithms, linux is it
because you can't even get to that stuff in Windows. Games? Wine is quite
functional, and many games work fine under Linux, others don't.
If you want complex one-off stuff, stick to the OS that the makers of such
packages cater to, which is usually Windows or Mac.
