I use the older pcie based 24io and 2488mk3. From my experience, windows driver quality lags behind the mac drivers by a few versions. Thier new thunderbolt based system had recently received windows drivers which donot support avb connectivity to the pc, where the mac drivers had just received this capability.

Their new thunderbolt based system had recently received windows drivers which do not support avb connectivity to the pc, where the mac drivers had just received this capability.

They also don't support ThunderBolt connectivity on the PC.  USB2 only.  I have had excellent results with a MOTU 2408 Mk3 and a 24I/O, but the PCI/PCIe stuff has now all been replaced with this new ThunderBolt stuff.  As the PC may never get it's act together with TB, I'm afraid that's the end of the line with MOTU for me.
 
The fact the TB still isn't supported properly in the PC world is going to come home to roost for PC DAWs, as new TB interfaces are going to push many PC DAW people back over the fence to Mac.  MOTU's TB/AVB stuff looks awesome, but would be severely crippled on the PC.

Man!All my DAW recording life, it has been a struggle trying to find a suitable interface that just plain works on  a PC running Sonar. At least 16 inputs to accommodate my preamps and mixer. Doesn't seem like it should be so tough. Just seems like, no matter what I think about, there are horror stories from people that have had problems. The temptation to go back to tape looks pretty inviting sometimes.... Nah! I lived many years with tape and, it has it's own set of headaches. Guess I'll just keep searching.

The real issue with multi-channel audio interfaces is that:

1. They are expensive
2. Driver support can disappear in as little as 5 years
3. You are left with a device you can't upgrade to the next version of Windows (no new drivers)
4. The computer interface goes end-of-life

I have already had many interfaces, including Gadget Labs 8*24, M-Audio 1010, and now MOTU 2408 Mk3 and 24I/O.  That is thousands of dollars in obsolete hardware.  The reality is that keeping your hardware up to date is going to cost you a lot of money if, like me, you need enough channels to record full bands, full drum kits, etc.  There is really no escape from this.
 
I always chuckle when people moan about the cost of upgrading Sonar - honestly, that's the cheapest part!

BRuys: Exactly! That was one nice thing about analog, once you bought it, it was what it was. No need for constant updates, worrying if it will still work with a new mixer or whatever.

Yeah, if you don't count the maintenance costs. I for one don't want to pay for a cap job on an analog console.

I can't complain. I got 10 years out of My 24io/2408mk3. I'm hoping to hang onto it until avb matures, maybe it will have a bit more longevity.

Yeah, everything's got it's upside and it's downside. I've had my Audiofire 12 for a long time. Before that, I had an Aardvark Q-10 for a long time. It's time to update and get more inputs. Twelve inputs ain't bad but, really need 16 at least, 24 at best. The UA, Lynx, etc. stuff is kind of out of my budget so, just trying to figure out something I can get. I was hoping some folks might chime in with what they are using that works.

Drivers are the real issue.  One day, we have to get to the point where everything is class-compliant, so even if the manufacturers stop updating their drivers, we can still use the hardware (even if it has a bit less functionality).
 
All the audio interfaces I've had to dump were 100% sound electronically, Imagine if I had to throw away my TV or Stereo because the company went bust or lost interest in the product?  Keeping equipped to record bands is an expensive exercise.  At least I don't have to throw away my expensive microphones, preamps, instruments, etc.
