I know it will be free for a limited time.  I still love 7 and my M-Audio cards still work fine. 10 graphically still looks like 8.  I wonder if 10 will be like Giveaway of the Day where you have to install it as soon as you get your license.
 
 There's still so much speculation as how W10 will be handled like a subscription service.
 
 Will it support legacy hardware that still has Vista and 7 drivers? 
 
 The MS compatibility tool for Windows 8 leaves hardware support unanswered.
 
 

I have the latest Win 10 Preview version 10130 installed.  Sonar Platinum and my Roland Studio Capture work OK in Win 10.  I just installed my Frontier Tranzport, in a Windows 7 compatibility mode, and it checks out OK in Sonar.  The last drivers issued for the Tranzport were Vista drivers.
 
Microsoft must be getting close to the "RTM" version.  The system I have Win 10 Preview installed on (on a separate hard drive) is a triple boot system, Win 7, Win 8.1 and Win 10 Preview.  All prior versions, "Windows 10 Preview" was listed in the OS selection menu.  With 10130 version it now reads "Windows 10".
 
 

Windows 10 will be the last OS.

 
Yeah, b/c everyone is going to Linux.

 Oh those same people who are with Charlie Brown waiting for the Great Pumpkin to arrive.  I can see those Mac users ditching Logic, Pro Tools and Avid for the "Great Pumpkin".

BTW there is a Windows update that runs in the taskbar to get Windows 10.

Rumor has it they are pushing it out this Summer.

You'll see, Lucy, you'll see.

That has really come a long way.  Unfortunately, we're in a catch 22.  REAL hardware support won't happen until users demand it from hardware makers, but there won't be many users until hardware support improves.
 
Still, I may one day set up a box to try it out.  It looks good for everything except audio.  On paper.
 
Actually the audio side looks good as well-on paper-for 2x2 at 48K/16.
 
FOSS will probably be an awesome thing for my grandkids (currently 5 & 3).  I'll focus on getting the youngsters to play instruments for now .  When they get older they'll probably have a full, multimedia iStudio on their phone(s), which will be implanted somewhere between their ears.  Will that make stereo obsolete?   

What is the catch with the "free" Windows 10? I've lived long enough to know that if something is free, there is a catch. I clicked the little icon and reserved a D/L for my W7 laptop. I guess I'll need to get my DAW out and set it up long enough to get it there too in case I want it.
I'm just not sure about this. The whole "free" thing worries me. Why is it free? What are they going to want from me later to make up for the "free" part?
Thanks.

No catch, MS wants to get everyone on Windows 10. They had some really bad press with Windows 8 (despite it actually being quite a good OS) and they don't want Windows 7 to turn in to another XP where people refuse to upgrade because they are convinced it is the last good OS ever. So they are trying to convince people to upgrade, and making the upgrade free makes it that much more tempting. They are hoping they can get the large majority of the Windows user base on to Windows 10 in a timely fashion.
 
We'll see if it works.

I don't have problems with Win7 x64 and don't currently see a good reason to chance issues just to get a 'free?' Win10 upgrade. I have no desire to give MS any more control over my OS than they currently have.( i.e. there is currently a little icon sitting at the bottom of my screen, which I can't get rid of, wanting me to get Win10...)
 
I wish Jim R. would chime in here with his opinion.
