There are lots of ways to change the window layouts. You can move things around, dock them or have them as tabs. You can save different layouts too.
When you say it didn't recognize your plugins, what do you mean exactly? Have you added all your VST folders and scanned them? I have loads of old and new VSTs and they all scan and show up and work just fine.
I did move some windows around etc. but the minimize thing was really annoying and the overall space felt tight with that bottom window. I work on a laptop and having a huge VST window open was never a problem with Sonar; you just minimized it and maximized it when needed. With Samplitude, I didn't see a minimize tab top right. Maybe there is a way...but first impressions were that there wasn't one. Also on Sonar, the ease of pulling windows up, down, left right, was so easy.
Regarding plugins: This is a problem with 32bit plugins in a 64bit install. I've read on Presonus forums of people who've had similar problems (didn't check out Samplitude forums as they seem to be wholey populated with ex-Sonar people :) It is solvable with JBridge, but when JBridge popped up in my Samplitude scan it didn't find BFDv1 or Trilogy. Reaper and Cubase had no such problem.
Ultimately, a DAW is like a car. They all do more or less the same thing, but it's a very personal choice. You either like it or you don't. I found Samplitude (like other Magix products) a bit Windows XP in feel. Slightly clunky design etc.. I'm sure it does everything right, but I wasn't blown away. I also was less than impressed with the synths. Nothing that I haven't already got. Many felt like bundled sounds that you get with Kontakt etc.
So, although the deal is an amazing price slash, I feel like a lot of us are considering buying it just because of the low price.
