I don't think backwards compatibility is critical. It is however important to not take stuff away at the last second.
Vista: Release Candidate 0 had the following functionality that they took away in Release to Manufacturers (RTM)
Shared Memory
Globally Named Pipes
This was a critical issue for my current employer. They developed their software and were ready for Vista, till the release came out. Then it just quit working. So all the R&D for Vista was wasted. There was a huge rush to fix it and it required a significant re-write. This hurt many software manufacturers.

The OS should be upgraded ONLY when it outgrows the hardware. Like on the Macs between version 6 and 7 (or was it 7 & 8) when they changed Processors at the same time they changed the OS. There new OS had an emulator to simulate the old processor. The programs written for the old OS ran slower on the slowest of the new hardware then the fastest of the old hardware, but it did run with no problems. And by the time I got enough money to get an upgrade, almost all programs had been upgraded to be optimized to the new hardware.
So I say we stick with XP until there are CPUs fast enough to emulate the x86 processors. Then we can run XP in a window for those old programs. Until everything gets optimized to the new CPU. This "new OS just because we haven't had a new one in a while" nonsense is just that, nonsense. I'm gonna wait for Windows 7 (If they actually do everything they say they are gonna do with it, but that is a rant for another time).

Interesting point. But you see the situation only from "software-execution-speed"-perspective.
You don't mention that the software (OS) does not only get slower but also more user friendly (hopefully  . That's the main reason to upgrade an OS imo. I would probably still switch if the new OS is 30% slower but I am 40% more productive with it. Even without new hardware.

Pretty much exactly why I do prefer Vista over XP. It's not that important that it's faster, or even fast at all. But it is important that it feels faster because it doesnt force me to wait through window repaints etc. it makes me feel like I am not waiting nearly as much, thus I am less annoyed. ergo: I am more productive.
So the speed at wich software executes is much less important than the speed at which software allows me to use it.

On 6/02/08 at 6:47 AM I posted to this thread:
"New OS should inherit from CListCtrl"
under the Heading "Under the hood is what counts', which perhaps addressed your original inquiry as the the appropriate handling of CListCtrl in any valid (new) O/S.

Can you please move your CListCtrl somewhere else? It's really not funny anymore. 
Post like these drives me to Ctrl+F4.
If I want to see a thing 100 times, this is Pulp Fiction.
Not another CListCtrl post (how about NACLP?).

Yeah, but it also means that you have to solve the same problem over and over again. I figure that once I solve a problem satisfactorily, I can move on to the next thing and not have to worry about that one again unless something is broken. I have enough to keep me occupied without the OS developers helping me out.

The emperor may put on new clothes, but down in the land of nitty-gritty, we keep solving the same problem (or two) over-and-over, anyway.*

I suppose I'm too much of a systems guy to view it that way. I look for the differences in the problem that make it interesting, and just updating to fix something that some OS guy broke because he thought it was funny isn't my idea of fun. I suppose that is why I pretty much only write analysis code for orbital mechanics and use them to solve interplanetary trajectory problems. Sure the same equations of motion are used everywhere, so once you have a tool written it is easy to solve the same problem over and over again with one set of software, but when you can't figure out how to do something with all the old stuff you go outside the box and try another type of solution. Since my software is only used by a handful of people, it makes everything easier.
Just as a note, I have a coworker who is still using a DOS Lahey Fortran 77 compiler, because he has a library that was released as a compiled version only. If there weren't a compatibility layer to be able to run that ancient 8-bit code, we would be forced to rewrite what is essentially a good and working piece of analysis software. As it is, I write new routines where I can that replace the functionality of that library and compile that into my less outdated Compaq Visual Fortran (F77/F90/F95) compiler. When I'm being generous, I'll even throw together a gooey and maybe even connect it to a DLL (as opposed to just writing out a file and running the console program).
A version of windows that broke compatibility with his ancient toolset would be an immediate deal-breaker.
I have to say that I do still miss the days of old when I wrote pretty programs that were user focused and utilized only state of the art languages / compilers.
