Around Y2k I bought GuitarTracksPro(2 or 3, can't remember). I loved that program, and it was all I needed for what I was doing, which was basically 4 tracking ideas for songs that my band could listen too. If we wanted to record for real, we paid our money and went to a local studio. When my laptop finally took its last breath last summer (07), and I had to go buy a new one, Vista had come out, and all PC computers at that time were coming with Vista. I couldn't find an XP computer anywhere, and I was being told I could not load XP on a new system as the hardware was not backwards compatible. I bought a Vista system at gunpoint, only to find that GuitarTracksPro would not work. I had to buy a new DAW. Guess what? Sonar was the only Vista ready choice at that time. That was fine with me, since I was used to the Cakewalk interface. I wanted to buy ProTools at the time, but here is why I did not.
1. Didn't want to drop $2,000 on an Apple, when I could get the same power in a PC for half of that or less.
2. Didn't like the choices in hardware (M box or nothing). Sonar let me shop Presonus, MOTU, Lexicon and others, who offer better choices.
3. Vista support (which has not gone so well I must admit.. me hates the Vista!)
4. Seemed to me that Sonar 7 had more to offer than ProTools LE. To me it was a case of "full software" vs a litght version for similar investment. ProTools HD is out of reach for me, and would be pointless anyway at my usage level.
5. Cubase did not seem to be an option at all at that time, since it did not support Vista, and I already decided not to go Apple.
I love Sonar, and will continue to use it for the reasons that many other people have listed.. custom layouts, no dongle (dongle's suck!) plug ins, softsynths, and I just like the workflow of it. In hindsite though, my Vista experiment has failed, and this OS drives me nuts. Too many wierd problems to chase down, and it just does not work as advertiesed. Nothing makes me more angry than to spend money to get a bunch of abilites and features that sound great, but don't actually work. I guess I am going to have to retrofit XP.
