I'm really glad I went for the deal now! Samplitude has been around since the early 90's so is mature.
It wasn't until I had bought it and installed everything that I really started to realize what a great DAW it is. I'm quite impatient when it comes to demos and unless it grabs me in the first few minutes I tend to lose interest and not try it again.
I'll be honest, I wasn't that impressed with the demo but thought I would get the deal because of all the stuff that's included. So the deal offers ridiculous bang for the buck. There's 70GB of content just for the Independence sampler alone and on top of that, there are loads of instruments, plugins as well as the Sound Forge Pro and SpectraLayers pro applications. That may be a good option if you have a slow internet connection. There is an option at checkout to get the content shipped on disks. You get so much with the suite that downloading and installing it all can take a long time. However, it didn't take much poking around for me to get it setup and start making proper music with it. At first sight, Samplitude looks confusing and rather alien to someone coming from Sonar. I hope this may help you if you are still looking for a new DAW to move to. I'll post my experiences so far with it and my comparisons with Studio One that I also have. After I bought into the Studio One crossgrade deal I discovered the crazy Samplitude X3 Pro Suite deal which I understand is being extended.
